How does current behave in a parallel circuit?

In a parallel circuit, the behavior of current can be understood by recognizing that each branch provides its own path for the flow of electricity. The total current entering the parallel circuit is indeed the sum of the currents flowing through each individual branch. This is a fundamental principle of parallel circuits, arising from the fact that the voltage across each branch remains constant and equals the source voltage.

As a result, each branch can draw a different amount of current based on its resistance, but the collective current flowing into the network of branches will always equal the sum of the individual branch currents. This relationship can be expressed mathematically using Kirchhoff's Current Law, which states that the total current entering a junction must equal the total current leaving that junction.

In summary, the correct answer reflects the inherent nature of parallel circuits where all paths contribute to the overall total current, allowing for each branch to function independently while still contributing to the overall current flow.
