What can be called a driven semiparallel RLC circuit consists of an AC emf E = E cos( ωt ) in series with a resistor R and a parallel combination inductor L and capacitor C . The parallel combination is connected back to the AC emf to complete the circuit. a) Draw a diagram. In the main circuit branch, there is a current I . In the inductor branch, there is a current I 1 . In the capacitor branch, there is a current I 2 . The currents are considered unknowns in this problem. The other quantities are considered knowns. b) Write down three equations that in principle can be used to solve for the currents I , I 1 , and I 2 . c) The solution for current I is, in fact, I = I cos( ωt − φ ) = E Z cos( ωt − φ ) , where (noncomplex) impedance...
