What are Parallel Resistors?

Parallel resistors are electrical components connected side by side in a circuit, where each resistor has the same voltage across it. The total current in the circuit is split between the resistors, with more current flowing through lower resistance paths.

The Formula for Parallel Resistance

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

1/Rtotal = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn

Where:

  • Rtotal is the total parallel resistance
  • R1, R2, R3, ..., Rn are individual resistor values
