# simulate RC and RL circuits in PSpice: tutorial 3

In this tutorial, I will explain you the working of RC and RL circuit. First the brief and concise introduction of capacitive and inductive circuits is provided explaining the effect of introducing each of them in a resistive circuit. After that the concept provided in introduction part is implemented with the help of PSPICE, and the theoretical results are compared with the virtual results of PSPICE which comes out to be same. At the end of the tutorial you are provided with an exercise to do it by yourself, and in the next tutorials I will assume that you have done those exercises and I will not explain the concept regarding them.

### Introduction to RC and RL circuits

The very basic circuits in electrical engineering are RC and RL circuits, these circuits are analyzed only to test the behavior of capacitor and inductor on current and voltage. The introduction of a capacitor in a simple resistive circuits results in the voltage lead of 90 degrees from the current. Similarly, if we introduce an inductor in a simple resistive circuit, the output current will be leading the output voltage by 90 degrees. This leading and lagging of current and voltage in case of RC and RL circuits will be explained in this tutorial.
