WebDec 17, 2011 · In a purely resistive circuit, voltage and current rise and fall together in a synchronous fashion. The reason this occurs is that a resistance continuously opposes the flow of current in a circuit regardless of whether the voltage is DC or AC. Because of this continuous opposition, current flows in phase with voltage. flw230Webmore. The voltage induced by the inductor is give by. L * dI/dt. This basically means that the voltage will be induced only when there's a change in the current. As time passes and the current gets constant in the circuit, dI/dt will turn to 0. Comment.
