1. A series circuit consists of 10,000, 20,000, and 30,000 ohm resistors connected in series across a 10-volt battery. Determine the current in the circuit?
2. Determine the propulsion force between two electric charges of 3 x and 7 x separated by a distance of 2 meters. (k=9,000,000,000
3. Determine the power consumed by a light bulb whose hot filament resistance is 240 ohms, when connected to a 120 volt source..
4. A 100 watt light bulb is operated continuously for a period of 10.5 days. Assuming power costs .12Cents per kilowatt-hour, what is the total cost to operate the light?
5. A transformer with 300 loops in primary coil is connected to a 120-V source. How many turns are required, in the secondary coil, to provide an output of 240V?
6. Some electric cars use a process of regenerative braking; that is, they turn electric motor into a generator and recharge the battery when slowing the car. Is it correct to say that energy spent to climb a hill could be completely recovered when returning to the starting location?
