Which of the following has only one loop for a current to flow through a) parallel b)series

Option (B) is the correct answer.

Explanation:

A circuit where current flows only in one path is known as a series circuit.

In series circuit current passing through each load or resistor is the same whereas total voltage is the sum of voltage passing through each load or resistor.

Thus, we can conclude that series circuit has only one loop for a current to flow through it.
