How To Find Equivalent Resistance In Series Circuit

By | July 19, 2022



It's a common question: how to find equivalent resistance in series circuits? In this Electronic Engineering 101 article, we'll discuss the basic fundamentals and introduce strategies for finding equivalent resistance in series circuits. Knowing how to calculate the equivalent resistance of a series circuit can be a valuable tool in your arsenal whether you're an amateur or a professional.

First off, let's define what a series circuit is. In short, a series circuit is when two or more resistors are connected to each other in a chain, with all of the electrical current flowing through each resistor in turn. In other words, the current is 'in series.' Each resistor in the chain affects the voltage, current, and the overall resistance of the circuit.

Now that we know what a series circuit is, we can look at calculating the equivalent resistance. To find the equivalent resistance in a series circuit, we can use Ohm's law, which states that the total resistance in a closed circuit is equal to the sum of the individual resistances. This means that to calculate the equivalent resistance, we simply need to add up all of the resistors in the series.

But what if one of the resistors is variable? In that case, we can use the equation R = R1 + (R2 x R3)/(R2 + R3). This equation accounts for the presence of the variable resistor and its effect on circuit resistance.

The last technique we'll explore is the 'bridge method.' This method can be used when there are three or more resistors in a series circuit. The bridge method is essentially a twist on Ohm's law, as it takes into account the voltage difference between two of the resistors. It involves subtracting the voltage of the first resistor from that of the last resistor, with the result being divided by the total resistance of the remaining resistors in the circuit.

Knowing how to calculate the equivalent resistance in a series circuit can be a useful skill for amateurs and professionals alike. Understanding the basics of Ohm's law, and knowing how to use the bridge method, can give those in the field a significant advantage. With these methods, you'll be able to quickly and accurately find the equivalent resistance in any series circuit.
