Electric Bell Mechanism and Functionality

The video tutorial explains the construction and working of an electric bell. It describes the components, including an iron core, coil, battery, and steel rod. The operation involves the iron core acting as an electromagnet when current flows, attracting a hammer to strike the bell. The circuit breaks when the hammer moves, stopping the electromagnet, and the hammer returns to its original position, completing the circuit again. This process repeats, causing continuous ringing until the switch is released.

What is the role of the steel rod in the electric bell?

• To produce sound

• To conduct electricity

• To hold the battery

• To act as a spring for the hammer

What happens when the switch in the electric bell circuit is turned on?

• The hammer stops moving

• The iron core becomes an electromagnet

• The bell stops ringing

• The battery disconnects

How does the hammer produce sound in the electric bell?

• By completing the circuit

• By vibrating the coil

• By hitting the iron core

• By striking the bell

What causes the circuit to break in the electric bell?

• The battery runs out

• The hammer moves towards the iron core

• The coil overheats

• The switch is turned off

What action causes the hammer to return to its original position?

• The battery recharges

• The switch is turned off

• The spring action of the steel rod

• The coil is removed

What ensures the continuous ringing sound of the electric bell?

• The coil is made of copper

• The hammer keeps hitting the bell

• The battery is fully charged

• The switch is permanently on

When does the ringing of the electric bell stop?

• When the hammer breaks

• When the switch is released

• When the coil is disconnected

• When the battery is removed
