Physics · Electric current: drift velocity, mobility and their relation with electric current
When the switch of an electric bell is pushed
When the switch of an electric bell is pushed
- A. Flow of the current stops through the electromagnet in the bell
- B. Current starts to flow through the electromagnet
- C. voltage decreases in the current flowing through the electromagnet
- D. None of the above
Step-by-step solution
When the switch is pushed, it closes the circuit, allowing electric current to flow through the electromagnet. This electromagnet then attracts a hammer that strikes the bell, producing sound.
