Slide 1

Resistors in parallel

Resistors that are connected to the same two points are said to be in parallel.

Slide 2

Resistors in parallel

A parallel circuit is identified by the fact that it has more than one current path (branch) connected to a common voltage source.

Slide 3

Resistors in parallel

Because all components are connected across the same voltage source, the voltage across each is the same.
