RLC Parallel Circuit (1) Applied alternating voltage: E = E max cos ωt Resulting alternating current: I = I max cos( ωt - δ ) Goals: Find I max , δ for given E max , ω . Find currents I R , I L , I C through devices. Junction rule: I = I R + I L + I C Note: All currents are time-dependent. In general, each current has a different phase I R has the same phase as E .
