Resistors in Parallel

The current in a circuit can be calculated by using Ohm's law: voltage equals resistance times current. In this simple circuit, the two resistors are in parallel, so the reciprocal of the effective resistance is the sum of the reciprocals of the resistances. This can be derived from the fact that the current splits equally over the two resistors. The current is then . No current flows when the circuit is open.
