A wind farm generates 2,286 kW of electrical power for a nearby community. The transmission wires have a total resistance of 1.06 Ω. Currently the electricity is generated at 5.07 kV, and a certain amount of energy is lost in transmission. If the voltage is increased to 9.25 kV, how much power, in kW, can be saved?

You have 2 resistors (R1=220. ohm, R2=100. ohm) that are in parallel with each other. These 2 are in series with a third resistor (R3=22.0 ohm). These resistors are in a circuit with a 5.00 V DC power supply (see circuit diagram in Figure 7, pg 47 in your lab manual). From this information, find Vtot, Req, Itot, I1, I2, I3, V1, V2 and V3.
