lle = 2+ (5 – 2)e-15t = 2+ 3e-15t A, %3D t > 0 %3D Example At t= 0, switch 1 is closed, and switch 2 is closed 4 s later. Find i(t) for t> 0. Calculate i for 1s 2 s and t= 5 s. t= 0 42 6 2 t=4 40 V 2Ω 5 H 10 V We need to consider the three time intervals t<0, 0St54, and t> 4 separately. For t<0, switches S1 and S2 are open so that i = 0. Since the inductor current cannot change instantly,

Sinusoids And Phasors

Sinusoids are defined as the mathematical waveforms that are used to describe the nature of periodic oscillations.

Circuit Theory

Electric circuits are a network that comprises of a closed-loop, which helps in providing a return path for the current through a switch. When the switch is activated, the load operates, and the current accepts a path to finish the circuit at a low potential level from the opposing high potential level. Electric circuits theory is a linear analysis that helps in establishing a linear relation of voltage and current for R (resistance), L (inductance), and C (capacitance).
