Best answer: How does an electric torch work short answer?

A torch consists of a simple electric circuit in which two or more cells are connected to a torch bulb through a sliding switch. When the torch is needed to provide light, the sliding switch is closed by pushing it forward so that the circuit is completed and the bulb of the torch lights up.

How does an electric torch work class 6?

Working of an electric torch

An electric torch has one or more dry cells that act as the source. The cells are connected through a switch to a small bulb. When the switch is pushed to the ON position, the circuit is complete and the bulb glows.

How does electricity flow in an electric circuit?

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
