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.
