# RL Series Circuit

_{R}and I

_{L}respectively. Since both resistance and inductor are connected in series, so the current in both the elements and the circuit remains the same. i.e I

_{R}= I

_{L}= I. Let V

_{R}and V

_{l}be the voltage drop across resistor and inductor. Applying Kirchhoff voltage law ( i.e sum of voltage drop must be equal to apply voltage) to this circuit we get,
