In this video, I describe what it means for devices to be in parallel and then explain what happens with voltage across and current through parallel devices. I provide a brief explanation of Kirchoff's Current Law and then derive the equation for equivalent resistance of multiple parallel resistors.

00:14 - Definition of parallel devices
00:47 - Voltage across parallel devices
01:05 - Current through parallel devices with analogy
02:46 - Kirchoff's Current Law
03:14 - Beginning of derivation of equivalent resistance for parallel resistors
05:30 - Parallel resistance equation
