Physics 2003 JAMB Past Questions - Question 37: The most suitable cell used for short interval switches in electric bells is

Correct Answer

C

Explanation

The most suitable type of cell used for short interval switches in electric bells is typically a carbon-zinc or alkaline battery. These types of batteries provide a relatively constant and reliable source of electrical power for short bursts of energy required by electric bells.

Carbon-zinc batteries are cost-effective and work well for low-drain devices like electric bells, whereas alkaline batteries have a longer shelf life and provide more energy, which can be useful for devices that are used intermittently. The choice between the two types may depend on factors like cost, availability, and the specific requirements of the electric bell.
