Series Resistor Calculator

What are Series Resistors?

Series resistors are electrical components connected end-to-end in a circuit, where the same current flows through each resistor. The voltage is divided across the resistors, with higher resistance components having a larger voltage drop.

The Formula for Series Resistance

The formula for calculating the total resistance of series resistors is:

\(R_{total} = R_1 + R_2 + R_3 + ... + R_n\)

Where:

• \(R_{total}\) is the total series resistance
• \(R_1, R_2, R_3, ..., R_n\) are individual resistor values

Calculation Steps

To calculate the total resistance of resistors in series:

1. Identify all resistor values in the circuit
2. Add up all the resistor values
3. The sum is the total resistance

Example

Let's calculate the total resistance for three resistors in series: 100Ω, 220Ω, and 330Ω.

\(R_{total} = R_1 + R_2 + R_3\)

\(R_{total} = 100\Omega + 220\Omega + 330\Omega = 650\Omega\)
