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
