Unit 5 Day 11: RL Circuits • Series RL Circuit Layout • Current and Voltage Response vs. Time when V0 is applied • Current & Voltage Response vs. Time during circuit discharge (Battery Removed) A Battery Connected to an RL Circuit • Consider a battery connected to a series RL circuit • The instant the switch is closed current begins to flow and it is opposed by the EMF induced in the inductor • Ass the current flows, there will also be a voltage drop across resistor R, VR=I·R (Ohm’s law), which will reduce the voltage drop across the coil • The current will rise gradually as more voltage is dropped across the resistor and less across the inductor, until steady state is achieved, in which all of the voltage drop is across the resistor Current Response of a Series RL-Circuit I SS t I I SS 1 e L where R • where is called the time constant RL-Circuit, Steady State, Battery Removed • Consider the same circuit, in steady state, with the battery removed. I I 0e t • The circuit reaches equilibrium again in approximately 4-5
