Understanding Parallel Resistance

In a parallel circuit, resistors are connected across the same voltage source. The key characteristics of parallel resistance are:

  • The voltage across each resistor is the same
  • The total current is the sum of individual currents
  • The total resistance is always less than the smallest individual resistance
  • Adding more resistors in parallel decreases the total resistance

Parallel Resistance Formula

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