1. (A): The lamp glows only when the circuit is complete.

(R): A complete circuit allows electric current to flow through the lamp.

Answer:

(a) Both A and R are true, and R is the correct explanation of A

2. (A): An incandescent lamp will not glow if its filament is broken.

(R): A broken filament stops the flow of current in the circuit.

Answer:

(b) Both A and R are true, but R is not the correct explanation of A
