In a series circuit, how will the current behave?

In a series circuit, the current behaves by flowing through the entire circuit without splitting. This is because all components in a series circuit are connected one after the other, forming a single path for the current to travel. As a result, the same amount of current flows through each component, and there are no junctions or branches for the current to divide into. The total resistance in the circuit is the sum of the resistance of each component, which directly affects the overall current determined by Ohm's Law (I = V/R).

Options that suggest splitting the current or increasing it at junctions pertain to parallel circuits rather than series circuits. In a series arrangement, there are no junctions where the current can split, and it must remain constant through each component until it completes the circuit. Similarly, referencing parallel circuits is not applicable here since we're discussing series circuits specifically.
