Write the answer of given problems:
Problem 1: Calculate the power dissipated when 5.5 V is applied across a resistor and 3 mA flows through it.
Problem 2: A machine uses 50W for 12 hours. How many kilowatt-hours have been used?
Problem 3: A certain stereo amplifier draws 3.2 A at 100 V when its output is 200 W. Calculate its efficiency and the power lost.
Problem 4: A certain series circuit is made up of a 1/8W resistor, a ¼ W resistor and a ½ W resistor. The total resistance is 2400 Ohms. If each one of the resistors is operating at its maximum power, calculate the value of each resistor as well as the value of the current through the circuit.
