In a circuit with an inductor, how does the current behavior differ from that in a resistive circuit?

In a circuit with an inductor, the current behavior is characterized by the gradual rise in current due to the inductor's inherent properties. When a voltage is applied to an inductive circuit, the inductor opposes changes in current flow through electromagnetic induction. This is known as inductive reactance. As the voltage increases, the current does not reach its maximum value instantly; rather, it builds up slowly over time as the energy stored in the magnetic field of the inductor increases. This gradual rise is represented mathematically by an exponential curve, where the time it takes for the current to reach a certain percentage of its maximum value is determined by the inductance of the coil and the resistance in the circuit.

In contrast, a purely resistive circuit allows current to respond instantaneously to a voltage change, resulting in a quick rise to its maximum value, which is the reason for the incorrectness of other choices. Additionally, the notion of a constant current does not apply to inductive circuits when voltage is initially applied, nor is there a situation of no current flow since the energy stored by the inductor allows the current to eventually change rather than remain absent. Thus, the correct understanding of inductor behavior leads to the conclusion that the current rises
