How is electric energy supplied to bumper cars?
The answers given to this question so far are only partially correct. The pole at the back of the car going to the overhead grid only provides half of the circuit. For the rest of the circuit, you might note that the cars run on top of a metal plate. There is another “brush” under the car that makes contact with the plate completing the circuit.
I totally agree with the first reply. The electricity flows from the ceiling, through the little wheel, down a wire in the pole, through the electric motor, and completes the circuit through electric contacts under the car (A wheel or a small metal brush), into the floor. If you look up, you’ll often see the little wheel sparking as it rolls along. One day in the park I had seen how one got broken and to fix it they entered just an online shop of auto accessories and ordered another wheel. It was so easy to fix it.
