Kirchoff’s Current Law MCQ Questions with Answers

by

Top 5 Basic Electrical Engineering MCQ on Kirchhoff’s current law with answers and solutions.

Kirchhoff’s current law is applicable to which type of circuits

Kirchhoff’s current law is applicable to which type of circuits:

  1. Series
  2. Parallel
  3. Any of these
  4. None of these

Correct answer: 2. Parallel

According to Kirchhoff’s current law, the summation of current entering a parallel nodes is equal to summation of currents leaving the node.

Node/Loop

KCL is applied to:

  1. Node
  2. Loop
  3. Any of above
  4. None of above

Correct answer: 1 .Node

Certain node has three incoming currents I1, I2, and I3 and two outgoing currents I4 and I5. The correct KCL statement will be

Certain node has three incoming currents I1, I2, and I3 and two outgoing currents I4 and I5. The correct KCL statement will be:

  1. I1 + I2 + I3 – I4 – I5 = 0
  2. I1 + I2 + I3 = I4 + I5
  3. I1 + I2 = I4 + I5 – I3
  4. All of these

Correct answer: 4. All of these

All above statements essentially represent one single equation

Nodal Analysis is based on

Nodal analysis is based on:

  1. Superposition principle
  2. Kirchhoff’s current law
  3. Kirchhoff’s voltage law
  4. Norton’s law

Correct answer: 2. Kirchhoff’s current law

KCL Circuit Problem

Certain circuit has three incoming currents having values 5 A, 9 A, and 1 A and two outgoing currents passing through two parallel resistors having equals values of resistance. The outgoing current flowing through first parallel resistor will be:

  1. 1 A
  2. 5 A
  3. 7.5 A
  4. 9 A
  5. Can’t predict from given data

Correct answer: 3. 7.5 A

For parallel resistors having equal resistance, the outgoing current will be equally divided.
