Have you ever been curious about electrical wiring, fuses, and circuit breakers? What is the reason that a circuit breaker trips or a fuse blows when an appliance such as a toaster or hair dryer is turned on? This week's lab is directly relevant to household wiring. 1. As the electric current through a wire increases, the wire can heat up. A Power supply fuse is a device that limits the electric current in a circuit, protecting against (electrical outlet) the danger of fire. It does this by creating an open circuit when the current Fuse through the fuse reaches a limiting value. Applicance 1 Using the symbols shown at right, design an electric circuit that would allow multiple appliances to function normally but would also best protect 2 Applicance 2 against fire hazard. Explain your thinking. etc. 2. Five identical light bulbs are connected in Circuits I, II, and B III shown at right. The batteries are identical to one A another and are ideal. III a. Rank the brightness of bulbs A-E from greatest to smallest, and explain your reasoning. b. Rank Circuits I, II and III from greatest to least according to the current through the battery. Explain
