In a series circuit, what effect do multiple loads have on overall current?

In a series circuit, the overall current is affected by the total resistance of the circuit, which is the sum of the resistances of all the loads connected in the series. When you add multiple loads (or resistors) into the circuit, each load contributes to the overall resistance. According to Ohm's Law (I = V/R), as the total resistance increases while the voltage remains constant, the overall current decreases. This means that the current flowing through the circuit is inversely proportional to the total resistance: as resistance increases with the addition of multiple loads, the current flowing through the circuit decreases. Thus, in a series circuit with multiple loads, the overall current decreases.
