In a parallel circuit, what is true about the total current?

In a parallel circuit, the total current is characterized by being the sum of the currents flowing through each branch. This occurs because the branches are connected independently across the same voltage source, allowing each branch to receive a portion of the total current based on its resistance. According to Kirchhoff's Current Law, the total current entering a junction must equal the total current leaving that junction. Therefore, by adding the currents in each individual branch, you arrive at the overall current flowing through the circuit.

This understanding is crucial for analyzing parallel circuits, especially when calculating load distribution and ensuring that components can handle the respective current levels without exceeding their rated capacities. Each branch can draw different amounts of current while still contributing to the overall current flowing through the circuit.
