The pulse width relative to a circuit’s time constant determines how it is affected by an RC and RL circuits. The purpose of this experiment is to 1. simulate the circuits by using components from the PSPICE library and, 2. analyze obtained graphs and results. Theory and Methodology: Time Constant (τ): A measure of time required for certain changes in voltages and currents in RC and RL circuits. Generally, when the elapsed time exceeds five time constants (5τ) after switching has occurred, the currents and voltages have reached their final value, which is also called steady-state response. The time constant of an RC circuit is the product of equivalent capacitance and the Thevenin resistance, τ = R×C (1) The time constant of an RL circuit is the equivalent inductance divided by the Thevenin resistance, τ = L/R (2) Time Period (T): Time required to complete one cycle is called Time Period or the length of each cycle of a pulse train is termed its time period (T). Pulse width (tp): The pulse width of an ideal square wave is equal to half of the time period.
