STUDENT NAME: DATE: RESULT: CY / CN. Series and Parallel Circuits In a series circuit: I R 1 R 2 the same current flows through each resistor. 86 Prelab 16: Series and Parallel Circuits Name: 1. Basically, a resistor limits the flow of charge in a circuit and is an ohmic device where V=IR. I p = V p /R a + V p /R b; I p = V p [ 1/R a + 1/R b] I p = V p /R parallel; Here, we take R parallel to be the parallel equivalent of the two resistors in parallel, and the expression for R parallel is: 1/R parallel = 1/R a + 1/R b There may be times when it is better to rearrange the expression for R parallel. Dorf and J. Therefore the resistance R is viewed as a constant independent of the voltage and the current. 5 amp flowing through it. A circuit has one battery and two light bulbs in parallel.
