Consider the following circuit with a potential of E=120V cos(wt) placed across its ends: (i) Compute the potential as a function of time across A and B with the switch S open? What is the value as S tends to infinity. (5 points) (ii) Now S is closed, repeat (i). Does anything funny happen as the circuit evolves? (5 points) 1 R1 R1 L L S A B 52.Assuming the current is through an LRC circuit is given by I(t)=I0 cos(wt). Derive the expression for the potential as a function of time. Also, derive an Ohm's like law using Impendance. 2
