Series & Parallel Calculator
Calculate the total resistance for series and parallel connections.
Series Connection
In a series circuit, resistors are connected end-to-end. The same current flows through each resistor, and the total resistance is the sum of all individual resistances.
Rtotal = R1 + R2 + R3
