Objectives To perform a transient analysis of RC & RL series circuits using Multisim Electronic Workbench. 2. Basic Information 2.1 Response to an AC forcing function: The complete response of first order RC and RL circuits with AC forcing function is given by )tancos( )(1 ) )(1 )0(()( 1 2 / 2 ωτωτ ωτωτ τ −− − + + + −= XmeXYtY tm The above equation shows that the response to a forcing function consists of two components, namely, the exponentially decaying component, called the transient component and an AC component called the AC steady state component, because this is the value to which the complete response will settle once the transient component has died out. We emphasize this by writing. ssxsient yyty +=)( Where ωτφ ωτ ωτ ωτ τ 1 2 / 2 tan )(1 )cos( )(1 )0(( − − −= + = Φ+= + −= m m inss tm xsient xy yy exyy the quantities my and Φ are called respectively ,the amplitude and the phase angle of the steady- state component. docsity.com 3 3.
