Your household is connected to a 240 V power line. Your 13A plug fuse blows, and you replace it with the readily available 5A fuse. You connect your 75W TV and 500 W fridge through the fuse. Determine the rating of a washing machine that will blow the fuse when added to the circuit.

An electrical device runs using power supplied by two 12.0 V batteries connected in series. The resistance of the device is measured to be 5.40 Ω. If the device is used for 1 day, determine the total energy it takes from the batteries.  

A section of the circuit of an electrical appliance is shown below. Determine the power supplied by the 13.5 V power supply.

Consider a small manufacturing plant where the machines collectively consume 80 kWh of electrical energy daily. If the electrical supply to the plant operates at a voltage of 220 V, determine the total electrical resistance of the plant.

What is the comparison between the total power delivered to the resistors when they are connected in parallel and when they are connected in series in a circuit with resistors measuring 3.2 kΩ, 4.8 kΩ, and 6.4 kΩ, and a power supply of 120 V?

A capacitor with a capacitance of 225 µF is initially charged using an 18.0 V battery. The capacitor is then connected to a 2.25 Ω resistor, by closing a switch, causing the energy to be discharged through the resistor. Determine the power dissipated in the resistor 125 µs after the switch is closed.

In an electricity pricing system based on time-of-day, where rates vary between peak and off-peak hours, let's analyze a situation where the electricity cost is \$0.21/kWh from 7:00 a.m. to 10:00 p.m. and \$0.09/kWh at all other times. What will be the yearly expense for electricity if a 3.5 kW air conditioner operates daily from 4:00 a.m. to 8:00 p.m.?
