Question

name the portable electric lamp which works with cells.​

Answer 1

Answer:

A torch is a portable electric lamp which utilizes at least two cells to light a little bulb.

A torch is a practical example of a simple electric circuit. It is an electric device that emits light. It consists of a bulb, electric cells, a switch, a reflector, and a cylindrical shape casing. Bulb: The bulb emits light when electric current flows through its filament.

Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go out. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs.

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.
