All electronic and electrical calculators Tools are developed and coded with proper and exact equations found in the circuit theory books and physics. So without manual checking you can get the exact and accurate value at the finger tips.
Resistor Value, Color Code & Divider Calculators
In Resistor based confusions occurs in color code and its resistance value, So you can use our free online Resistor color code checker tool in live band color and voltage divider output voltage, parallel resistor value finding and many more useful tools, the important are listed below,
Resistor Color Code Checker to Check Unknown Band on the Resistor
Most of the hobbyist not know the band value, because some time is difficult to remember the color code and multiplication method. An online resistor color code checker tool helps you to find out the color band based resistor value.
In 3 band resistor the first 2 bands are the digits the third band is the multiplier and 4th band is tolerance. The tolerance band usually label as in Gold or silver. For 10K resistor First band is Brown 2nd band is Black and its multiplier is Orange as 1000. 10×1000 = 10,000K.
Voltage Divider Calculator Tool to Determine the Divider Output voltage or Resistor Value
Two Resistors are series connected and The one end connected to the positive voltage supply and the other end of the resistor is connected to the negative supply of the resistor. The Vout is taking from the Resistor 1 and Resistor 2 joining point. This is called Resistor voltage divider.
The Input DC voltage is less than the output voltage. This voltage divider configuration is mainly using for reference voltage to the microcontroller IC like Arduino, PIC IC and Op amp IC. The online Calculator tool to calculate voltage divider is easy and quick way to find out either Resistor value or Vout value.
Parallel Connected Resistor Value Calculate
The parallel resistor calculator is simple and easy to calculate but its in different values and number of connected resistors above 3 make you confusion and difficult to calculate in mind. So a simple online parallel resistor vale finding tool helps you top solve the problems.
In this calculator tool, you can enter the each value of parallel connected resistor and click calculate button to get the result faster. This Tool helpful for many electronic engineering students. You can also add many resistors and calculate its total parallels resistance value just a click.
3 Digit SMD Resistor Resistance Value Checker
Most of the modern electronic circuits are designed using SMD components. The Tiny 3 Digit Resistor code is easy to understand but, beginners in electronics struggling to identify the components value.
So this SMD Resistor Resistance Calculator tool will helps to find out any 3 digit resistors value. From the three digit, the first and second digits are the numbers and the third one is the multiplier. For 103 labelled on the surface means 10 x 10,00 = 10,000K ohms.
LED Series Connecting Resistor Electronic calculator Tool
Connecting LED directly to the 12V DC or 5V DC will permanently damage it. The LED needs 1.5-2V Dc and 10-20mA current. To limit the current we are using the resistors series connection with the LED. The value of Resistor is depends on the type of LED and input voltage.
Manual calculation in every time is difficult, so the online LED series connected Resistor calculator tool easily find out the resistor value. Just input the DC supply voltage and LED forwarding current to calculate. This Simple Electronic calculator tool helps me lot and save time before connecting with wrong resistor value to the LED.
Helpful Capacitor Values Conversion Tools
The online capacitor value converter tools are very helpful for beginner to advanced engineers in electronics. Because little bit difficult to remember all the multiplication and conversion value of capacitors. If you see a capacitor you can directly enter the value to convert it into different units without any manual calculations. important Capacitor Online Converters are given below,
Convert pF to nF to uF Easily with Online Tool
The capacitors values are represented in pF, uF and nF. In many electronics board you can see different types of capacitor with different values. In electronic circuit development stage capacitors need to change and converted to its original unit to other units. So the easy capacitor converter Tool will helps me a lot to do this.
Enter the disc capacitor value in the converter tool to see the corresponding nF value and uF value. you can also convert the unit from pf to nf and nF to pF.
pF to nF Converter for Disc to Box capacitor Value Conversion
pF is called Pico Farad and nF is called Nano Farad. Swapping this values each other is very important in audio circuits and power supply circuits. So the dedicated pF to nF conversion online Tool helps easily. Just we need to know any one value and swap it easily. example calculation given below,
- The conversion formula for PF = nF x 1000
- if pf value is 104 = 10,0000 then the nF value will be 10,000/1000
- So, nF = 100nF
nF to uF Conversion using Online Tool
The nf is called as Nano farad and the uF is known as micro farad. To conversion we can use the dedicated online converter tool is called as nF to uF conversion tool. No need to manually calculates the values, just enter any value and swap it to other unit.
1nF is equal to 0.001uF. The common daily usage capacitor values are given below,
- 1nF = 0.001uF
- 10nF = 0.01uF
- 100nF = 0.1uF
- 220nF = 0.22uF
Audio Amplifier and Speaker Testing Tools
For designing perfect audio amplifier circuits and designs we need special mathematical solutions. The Subwoofer and speaker testing using Bluetooth board is older method, now we have dedicated Frequency adjustable audio generator tools like subwoofer test tools are available. Some of the important and useful electronics audio tools are given below,
PMPO to Real Audio Power Converter Tool
The PMPO is not a real audio output value. it is a marketing tactic used by the companies to sell their amplifier or speakers. The real audio output value is represented in RMS value. I recommended to use the online PMPO to RMS converter Tool to know how much PMPO value is equal to the RMS value.
The Tool is helpful for converting your home audio system PMPO value to the true wattage of the amplifier or speaker.
Online Electrical Calculators for Beginners and Engineers
The specially designed electrical calculator online tools are easy to use everyone. The list of calculators are Amps to watt converter tool, Motor hp to Amps calculator for both single phase and 3 phase. The popular and daily needed electrical calculators are given below,
Amps to Watts Conversion Calculator Tool
Amps is the unit of current and watts is the unit of power generated. The general formula to find out the Watts = Voltage x Ampere.
In this online Ampere to watts calculator tool helps to quickly find out the value. This calculation is simple but more decimal values are comes better to use the online free calculator’s.
- Example calculation, Voltage is 230V Ac and current usage is 3A then the wattage will be,
- 230 x 3A = 690 watts.
How Much Electricals Power Motor Draws? HP to Amps Calculator Tool
HP means the horse power, using this known HP value we can calculate the current usage of motor in ampere. 1HP motor is equal to 746 watts.
So the calculation for Amps = HP x 746 / Voltage. This calculation id for DC motor. The equation will be change for Ac single phase and three phase motors.
To avoid the calculation errors and confusion i suggest you to check the online Motor HP to Amps calculator Tool for quick answers without any errors.
