a. Develop a microscopic model to explain why a conductor heats up when clectriccurrent flows through it. Sketch and describe it.b. Given that electric currents generate magnetic fields, why don't your keys getattracted to the power cords on electric appliances?c. Which energy tasks have the highest power requirements? How can you minimizethe cost of operating these appliances?d. If "too many" appliances are ON simultaneously, why might a fuse blow or a circuitbreaker trip? Hint: Appliances are connected in parallel. Recall what happens to themaximum current in a parallel circuit as more and more devices are added.e. Why do some appliances have 3-pronged plugs? Hint: The third prong is connectedto the appliance's chassis (metal frame) and plays a role only if, due to some failure,the chassis becomes electrically charged, possibly endangering its user.f. There are several ways to use less electric energy: (i) increase an appliance'sefficiency (perhaps by buying a newer model), (ii) partially or fully curtail usage ofsome appliances, (iii) substitute another fuel for some tasks. List some ways youmight do each of these in your home.

It refers to the amount of energy used to perform a specific task. It is measured in KWh or joules.
