If 5 V and 16 V power supplies are connected in series-opposing, what is the total voltage?
A)
11 V
B)
16 V
C)
21 V
D)
80 V

What happens to the current in the series circuit if the resistance is doubled?
A)
It becomes zero
B)
It becomes double its original value
C)
It becomes half its original value
D)
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?
A)
Zero
B)
Infinite
C)
The value of the source voltage
D)
None of the above

Correct Answer :   Zero
