1. The problem statement, all variables and given/known data Given a series RLC circuit with a sinusoidal voltage input, find the effective voltage across each element. Given: 1) If the effective value of the source voltage is 1 V, the effective value of the current is 1 amp. 2) i(t) lags v(t) by 45 degrees 3) L=1H 4) w=2 rads/sec 2. Relevant equations Veff = [1/T * ∫ v^2(t) dt] ^ (1/2) Ieff = Im/√2 Veff = Vm/√2 3. The attempt at a solution Based on the information I know that: v(t) = Vmsin(2t) i(t) = Imsin(2t-45) Not exactly sure where to go from here especially since R and C aren't given, but I'm assuming you don't need these values or can find out based on the information already given.
