What is the total current from a four-branch parallel circuit with branch currents of 4 A, 5 A, 5 A, and 6 A?

To find the total current in a four-branch parallel circuit, it is essential to understand that the total current is simply the sum of the individual branch currents. In this scenario, the branch currents are 4 A, 5 A, 5 A, and 6 A.

To calculate the total current, you would add these values together:

4 A + 5 A + 5 A + 6 A = 20 A.

This means the total current flowing through the parallel circuit is 20 A. Each branch operates independently, and the total current is the summation of the currents through each branch.

Therefore, the correct answer reflects the proper method of calculating the total current in a parallel circuit, confirming that the answer is indeed 20 A.
