Question

When the switch of an electric bell is on then electric current in it :

• A. Flows and stops in succession
• B. Flows continuously
• C. First flows in one direction and after sometime in other direction
• D. Flows in beginning and then stops forever

Answer 1

The correct option is A Flows and stops in succession

The bell works on the principle of electromagnetism which says that when an electric current flows through the coil, the rods become magnetic and attract a piece of iron attached to a clapper. And the clapper hits the cap and comes back as the current stops, and hence the bell rings. So the current flows and stops in succession. And in this way the bell rings.
