1. A 20-volt relay has a coil resistance of 200 ohms. How much current does it draw?
2. A series circuit has 1200-ohms of total resistance with 12 V as the power supply.
What is the total current of this circuit?\
3. A transformer is connected to 120 volts. Find the current if the resistance is 480-ohms?
4. If a small appliance is rated at a current of 10 amps and a voltage of 120 volts, the power
rating would be Watts. (P = I V )
