For the Platinum RTD that I am using α = 0.385 Ω/°C, when I plug this value into the equation for calculating the compensation resistor R2 I now get sensible a sensible value of 23.1k Ω. Also, when I simulate the circuit at different cold junction temperatures the tem...
but we must take into consideration the color of the LED as well as the wattage rating of the required resistor, and the number of LEDs in the circuit. We hope reading How to Calculate Resistor Value for LED Lighting gives you what you would need for your project. ...
To use a pull-up resistor, you’ll need to locate the input line that connects to an input device. Once located, you’ll want to calculate how the value of your resistor using the formula discussed earlier. If your circuit doesn’t really require much precision, you can simply use resist...
Determine the total number of resistance in the circuit. You measure resistance in ohms, which is expressed using the Greek letter omega. If you measure that there is a resistor with 3 ohms of resistance in this circuit and another with 2 ohms of resistance, that means that the circuit has...

Honyone teach you how to calculate the resistance value of switch neon in some electrical devices, to use a light switch and led, with the neon as the indicator lamp, because the factory initial voltage of Neon is invariable. To use in a circuit higher than the voltage used, it is necess...
Reduce the circuit below to one resistor and one capacitor. Example 1 Step 1: Look for components that can be combined in series and find their equivalent resistance or capacitance. The resistors are in series and we calculate their equivalent resi...
Hence, make sure of the resistance before using it. To calculate the required length of wire for a particular value of shunt resistor, use the below equation. For example, if you require a shunt of 0.5 mΩ and use 10 AWG wire, put the above values in this equation. ...
