The circuit below dissipates 5.25 mW. What is the voltage supplied by V1? The figure consists of schematic diagram of three resistors connected in series with a DC power supply labeled as V1 with an unknown voltage value with a return path to the negative terminal of the power supply also connected to ground. The circuit is grounded at the negative lead of the power supply. The resistors are labeled and valued as follows: R1 equals 1 kOhm. R2 equals 91 kOhms. R3 equals 22 kOhms.
