Question

Choose the correct statement for a bulb connecting in an electrical circuit.
Statement (i) : The bulb glows only when the switch is in ON condition.
Statement (ii) : The bulb does not glow when the switch is in OFF condition.

• A. Only statement (i) is correct
• B. Only statement (ii) is correct
• C. Both statement (i) and statement (ii) are correct
• D. Both statement (i) and statement (ii) are incorrect

Answer 1

The correct option is C Both statement (i) and statement (ii) are correct

Switch is a device which either breaks or completes the circuit. When the switch is in ON condition, the electric current passes through the bulb and makes it glow. On the contrary, when the switch is in OFF condition, it breaks the circuit. Therefore the electric current does not flow through the circuit and hence bulb does not glow in this condition.
