How To Find Voltage Across A Resistor In Parallel Circuit

By | February 3, 2023



Understanding the properties of parallel circuits can be a challenging but exciting journey for anyone getting into basic electrical engineering. Learning how to find voltage across a resistor in a parallel circuit is an important skill that can make all the difference when it comes to designing efficient and powerful electrical systems.

When dealing with a simple parallel circuit, the voltage across the resistor has two possible values - the same as the source voltage or a fraction of the source voltage. How you calculate the value depends on the number of resistors in the circuit.

The easiest way to understand how to find voltage across a resistor in a parallel circuit is to consider the circuit like a ladder. If there is only one resistor, then the voltage is simply equal to the source voltage. However, if there are multiple resistors in the circuit, then each one will have a fraction of the source voltage. To find out how much voltage each resistor will receive, you'll need to calculate the total resistance of the circuit, then divide the source voltage by the total resistance.

It's also possible to calculate the voltage drop directly across a single resistor in the circuit. This is done by multiplying the resistance of the resistor by the total current flowing through the circuit. The result of this calculation is the voltage drop that the resistor experiences.

Of course, these calculations assume that the circuit is working properly. If the circuit is not operating correctly, then the calculated values may not be accurate. This is why you should routinely check the voltage readings in a circuit in order to maintain a safe and reliable environment.

Learning how to find voltage across a resistor in a parallel circuit is an important step for anyone looking to become a successful electrical engineer. Although the details of the calculations can be complicated, it is possible to understand the basics of the process with a little bit of practice. By following these steps and with the help of a few diagrams, you'll soon be able to solve parallel circuit problems with ease.
