For 2 resistors in parallel you can use this formula. Rp = (R1 * R2)/R1 + R2 (only for 2 resistors in parallel) Tags Electroschematics. P. Marian. About P. Marian. I love all about electronics, ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. The currents in the branches of a parallel circuit add up to the supply current.

Resistors (Ω) oppose current, are color-coded, and connect in series (Rt = ΣR) or parallel. Current-limiting resistors protect LEDs.

5 comments on “ Parallel Resistors ” jimfordbroadcom December 10, 2013. Yeah, a handy program to have. I just did the algebra from the parallel resistor formula RP= R1*R2/(R1 + R2) and came up with R1 ...
