The diagram in Fig. shows the electrical system of a car to operate the two head lights and two rear lights by a switch. shows a connection to the body of the car. The diagram shows only one lead from the battery to each bulb, but a complete circuit must have two leads. How does the current get back to the battery?
Text Solution

One lead of the battery and one terminal of the appliance (i.e., bulb) is connected to the body of the car (i.e., to the earth). The current gets back to the battery through the body of the car (i.e., earth). Thus the body of the car behaves like the other lead.
