Most recreational vehicles and boats have the capability of operating electrical appliances using a 12-V battery, which either requires the use of special appliances designed to run on 12-V DC or the use of an inverter that converts direct current to alternating current as used in our homes. Consider one such 12-V DC circuit in which the following appliances and devices are being operated simultaneously on the same circuit: a 40-W minirefrigerator, a 150-W hair dryer, a 200-W blender, and three 15-W lightbulbs. Determine
(a) the current through each of these appliances/devices and
(b) the minimum fuse required to handle this load. (Fuses are rated according to the maximum current they will allow.)
