# How To Calculate Total Resistance In A Series Parallel Combination Circuit

By | February 18, 2023

When it comes to electrical circuits, understanding how to calculate total resistance can be a complicated task. It’s especially challenging when dealing with a series parallel combination circuit. Fortunately, knowing the basics of how to calculate total resistance in a series parallel combination circuit is not as difficult as it may seem on the surface.

The key to understanding how to calculate total resistance in a series parallel combination circuit lies in recognizing the differences between series and parallel circuits. In a series circuit, each component has an impact on the overall resistance of the circuit. That means if you change one component, the entire circuit’s resistance changes. On the other hand, in a parallel circuit, each component has no effect on the overall resistance. So, if you change just one component, the total resistance stays the same.

Once you understand the difference between series and parallel circuits, calculating total resistance in a series parallel combination circuit becomes much easier. To start, identify which components are in parallel and which ones are in series, then use Ohm’s law to calculate the resistance of each component. For example:

R_total = R_1 + R_2 + … + R_n

Where R_1, R_2, etc. represent the resistances of each component in series.

Next, calculate the resistance of each component in parallel by using the following formula:

1/R_total = 1/R_1 + 1/R_2 + … + 1/R_n

Once you have the resistance values of each component, add them together to get the total resistance of the series parallel combination circuit.

It’s important to keep in mind that in order to calculate total resistance in a series parallel combination circuit effectively, you must be able to identify which components are in series and which are in parallel. If you don’t accurately identify them, your calculation may be off.

Calculating total resistance in a series parallel combination circuit can be complicated, but if you follow these steps, you should be able to do it with ease. With the help of Ohm’s law, you can quickly calculate the total resistance of a complex circuit. With a little practice, you’ll become a pro at identifying and calculating series parallel combination circuits in no time!
