Question

A break in the filament of an electric bulb means:

• A. a break in the path of the current between the terminals of the cell
• B. An incomplete electric circuit
• C. the bulb is fused
• D. All of these

Answer 1

Answer: (A), (B), (C)

The correct options are
A

a break in the path of the current between the terminals of the cell

B

An incomplete electric circuit

C

the bulb is fused

A break in the filament means that the bulb is fused. In this state if it is connected to any circuit then it would cause a break in the path of the current, as the charge carriers do not get a closed path, i.e. it will leave the electric circuit incomplete.
