Circuit Description:

This is a parallel circuit with four resistors connected in parallel.

When the switch is closed to source voltage, current flows from the positive battery post through R1, R2, R3 and R4 individually the circuit is complete with the ground which is connected to the ground side of each resistor then is completed at the negative battery post. The following measurements and calculations are made using Ohms Law and the Parallel Circuit rules.
