What happens to the current in a circuit if the total resistance of a series circuit increases?

In a series circuit, the current flowing through the circuit is inversely proportional to the total resistance, according to Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), expressed as I = V/R. When the total resistance increases while the voltage remains constant, the overall current in the circuit decreases. This is because the increased resistance impedes the flow of current, resulting in less current being able to pass through the circuit. Essentially, as resistance increases, the available pathway for current flow becomes narrower, which leads to a reduction in the amount of current that can be sustained in the circuit.
