The formula for the equivalent resistance of resistors in parallel that is given above can be extended to any number of resistors by adding another term to the denominator. If two resistors are in parallel, this formula can be reduced to a much more convenient form. Simplifying, the equivalent resistance of two resistors in parallel is given by

The equivalent resistance will vary for the different connections because the series-parallel combinations vary, and hence the current will vary. Set Up: First calculate the equivalent resistance using the series-parallel formulas, then use Ohm’s law (V = RI) to find the current. Execute: (a) 1/R = 1/(15.0 Ω) + 1/(30.0 Ω) gives R = 10.0 Ω.

The equivalent resistance for resistors in series is given by the formula. Req = R1 + R2. Two resistors are said to be in parallel if the current is split between them and them recombines after passing through them. The equivalent resistance for resistors in parallel is given by the formula. 1/Req = 1/R1 + 1/R2
