Question:
An electric heater works on 120 V and draws 3 A of current. How much power does it use?
A 56 resistor is connected across the terminals of a 1.5 V battery. What is the power dissipation in the resistor?
The maximum voltage is 1 V and the maximum current is 1 A in a given resistor. Should a 1 W or a 2 W resistor be used? Why?
A 50 load uses 1 W of power. What is the output voltage of the power supply?
How much average current can be drawn from an 80 Ah battery for 10 h?
A certain power supply provides a continuous 2 W to a load. It is operating at 60% efficiency. In a 24 h period, how many kilowatt-hours does the power supply use?
