Question

Explain how electric power and electrical energy are related. 2. Discuss why fuses and circuit breakers are used in household circuits. 3. Explain what determines the current in each branch of a parallel circuit. 4. Explain whether or not a fuse or circuit breaker should be connected in parallel to the circuit it is protecting. 5.
