Question

Current flows in a circuit when


a. a switch is opened


b. a switch is closed


c. the switch is either open or closed


d. there is no voltage

Answer 1

Answer:

a. a switch is opened

Explanation:

current flows in a circuit when switch is opened

Answer 2

Current flows in a circuit when b. a switch is closed.

Explanation of the answer:

• When the switch is off or closed, a closed loop path is formed or created in the circuit.
• the switch is off or closed, a closed loop path is formed or created in the circuit. If there is any source or charged capacitors available or present in it then a current starts flowing as soon as the switch is closed.
• When Switch is closed in any circuit it serves or acts as a closed circuit so current flows only in a closed circuit.
• Hence, the correct answer among all the options is option b. a switch is closed.
