Kirchhoff's voltage law states that:

A)
the algebraic sum of the resistances is equal to the sum of the voltages
B)
the algebraic sum of the individual currents around a closed loop is zero
C)
the voltages developed across each element in a series circuit are identical
D)
the sum of the voltage drops in a series circuit is equal to the total applied voltage

Correct Answer : Option (D) :   the sum of the voltage drops in a series circuit is equal to the total applied voltage

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

Correct Answer :   11 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

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.
