Question

Electrical component that limits the flow of electrical current in a circuit is called

• A. switch
• B. resistor
• C. electric cell
• D. electric bulb

Answer 1

The correct option is B

resistor

Explanations for correct option:(b)

1. Resistor is an electrical component that resists or opposes the flow of electric current in a circuit .
2. A resistor is made up of conducting wire whose resistance depends upon type of material, length and thickness of wire.

Explanations for incorrect options:(a),(c),(d)

1. switch is simple device to turn ON and OFF electric current in a circuit by closing or opening it.
2. An electric cell is portable source of electricity that produces small amounts of electricity; its not a resistor.
3. Electric bulb is an electrical component which glows when current passes through it.

Hence, the correct option is (B).
