# How To Find An Unknown Resistor In A Parallel Circuit

By | July 14, 2022

Resistors are an essential component of many electrical circuits, as they're used to control the current running through them. If you're trying to troubleshoot an issue in a parallel circuit, you may need to know how to find an unknown resistor. To help you out, we've put together this guide on how to identify an unknown resistor in a parallel circuit.

The first step in finding an unknown resistor in a parallel circuit is to identify all of the known resistors. This can be done by measuring the voltage across each of the resistors in the circuit with a voltmeter. Once all of the known resistors have been identified, the next step is to calculate the total resistance of the circuit. This can easily be done using Ohm's Law, which states that the total resistance of a parallel circuit is equal to the reciprocal of the sum of the reciprocals of each individual resistor.

Once the total resistance of the circuit has been calculated, the next step is to determine the value of the unknown resistor. This can be done by measuring the voltage drop across the unknown resistor with a voltmeter and calculating the resistance based on Ohm’s Law. Alternatively, you can use Ohm’s Law to calculate the total current of the circuit and then calculate the total resistance of the circuit with the known resistors. The difference between the total resistance of the circuit with the known resistors and the total resistance of the circuit without the unknown resistor will give you the value of the unknown resistor.

Finally, it's important to remember to always double-check your calculations and make sure that the values of the resistors are within an acceptable range. If they're not, it could indicate an issue with the circuit or possibly an incorrect reading from the voltmeter.

By following the steps outlined above, you should now be able to easily identify an unknown resistor in a parallel circuit. Remember to always double-check your calculations to ensure everything is accurate and in order.
