In a series circuit, when more resistors are added, the total resistance increases. This increase in resistance affects the total current in the circuit according to Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). Therefore, when the resistance rises due to the addition of resistors, the total current in the circuit decreases, provided the voltage remains constant.

As additional resistors are introduced sequentially, the cumulative effect is an increase in the overall resistance, leading to a reduction in the flow of current through the circuit. This relationship illustrates how current behaves in series configurations and reinforces the importance of understanding resistance and its impact on current flow in electrical circuits.
