b. One of the thicker wires is attached to the metal case of the bulb
c. The other thicker wire is attached to the tip at the center of the base
d. All are true
Answer:
(d) In a bulb the filament is fixed to two thicker wires. One of the thicker wires is attached to the metal case of the bulb and the other thicker wire is attached to the tip at the center of the base.
Q.9. Two terminals of the electric cell connected to two terminals of the bulb
a. Provides a complete path for electricity to pass
b. Is known as electric circuit
c. Both (a) and (b) are correct
d. None of these
Answer:
(c) Two terminals of the electric cell connected to two terminals of the bulb provide a complete path for electricity to pass and it is known as electric circuit.
Q.10. Current passes through a circuit
a. Only when the circuit is complete
b. There is no gap between the cell and bulb and again between bulb and the cell
c. There is a gap between the bulb and the cell
d. Both (a) and (b)
Answer:

Q.15. Electric switches are able to break the electric circuits because
a. They form a gap between the terminals of the bulb and the cell
b. Air in the gap does not allow the current to pass through it
c. Disconnects the bulb from the cell
d. All are correct
Answer:
(d) Electric switches are able to break the electric circuits because they form a gap between the terminals of the bulb and the cell. Air (an insulator) in the gap does not allow the current to pass through it and disconnects the bulb from the cell.
