A voltage across a series resistor circuit is proportional to?

Electrical and Electronic Engineering (EEE) : Series Circuits - Quiz(MCQ)

The power in the circuit

The value of the resistance itself

The amount of time the circuit was on for

The value of the other resistances in the circuit

Correct Answer : Option (B) : The value of the resistance itself

Explanation : V=IR hence the voltage across a series resistor circuit is proportional to the value of the resistance.

If 5 V and 16 V power supplies are connected in series-opposing, what is the total voltage?

11 V

16 V

21 V

80 V

Correct Answer : 11 V

What happens to the current in the series circuit if the resistance is doubled?

It becomes zero

It becomes double its original value

It becomes half its original value

It becomes infinity

Correct Answer : It becomes half its original value

Explanation : I=V/R. If R becomes 2R then I becomes I/2 i.e. half of its original value.

What is the voltage measured across a series short?

Zero

Infinite

The value of the source voltage

None of the above

Correct Answer : Zero

Explanation : A short is just a wire. The potential difference between two points of a wire is zero hence the voltage measured is equal to zero.
