Kirchoffs Law MCQ | Class 12 Physics | Enlight CBSE


1.Kirchhoff’s first law is which of the following?

1. KCL.

2. KVL.

3. Both 1 and 2.

4. None of the mentioned.

Answer: KCL. Kirchhoff's Current Law.


2. Kirchhoff’s laws do not apply to circuits with:

1. Parameters that are distributed

2. Parameters grouped together

3. Elements that are passive

4. Non-linear resistances

Answer: Kirchhoff’s laws do not apply to parameters that are distributed.


3. KCL is founded on the idea that:

1. A node has the ability to store energy.

2. There can’t be any charge accumulation at a node.

3. At the node, charge build-up is possible.

4. Accumulation of charges may not be feasible.

Answer: There can’t be any charge accumulation at a node because any charge that enters the node must exit immediately because it is not a circuit element.


4. In a network, the algebraic summation of voltages around any closed path equals:

1. 1

2. 0

3. Negative polarity

Answer: Zero. Kirchhoff's Voltage Law states that the algebraic sum of all voltage around a close path or loop is zero.


5. Kirchhoff law calculates which of the given electric parameters?

1. Voltage

2. Resistance

3. Current

4. Both 1 & 3

Answer both 1 & 3: Kirchhoff law calculates both Voltage & Current
