1. A current of 1.5A flows through a motor when it is connected to 120V. What is the resistance of the motor? 2. An electric heater, which has a resistance of 160, is connected to a 120V Source. What is the current flowing in the heater? 3. What is the potential difference across a 150 resistor when a current of 6.5A passes through it? 4. What is the resistance of a wire if a current of 36A passes through it when a potential difference of 6V is applied across the ends of wire?
