How To Find Unknown Resistance In Parallel Circuit

By | March 1, 2023



Resistance in parallel circuits can be hard to determine, but with the right steps, it is possible to find the unknown resistance in a circuit.

The first step to finding an unknown resistance in a parallel circuit is to draw a diagram of the circuit. This will help you to identify the components and how they connect to each other. It’s important to note that the resistance in a parallel circuit is not just the sum of all the individual resistors. Instead, the total resistance is lower than the lowest resistance value.

The next step is to measure the voltage at each component. By measuring the voltage at each component, you can calculate the individual resistances. For example, if you measure a voltage of 2V at one component, and a voltage of 6V at another component, you can divide the voltage by the current to find the resistance of each component.

Finally, you can use Ohm’s Law to calculate the total resistance. This law states that the total resistance is equal to the sum of the individual resistances. By adding the individual resistances, you can find the total resistance in the circuit.

Finding the unknown resistance in a parallel circuit may seem daunting. However, by following these steps and understanding the basics of Ohm’s Law, you can easily find the resistance in the circuit. Knowing the total resistance in a circuit can be helpful when troubleshooting or designing a circuit.
