1. The problem statement, all variables and given/known data A circuit contains only two of the three elements L,C ,R. When connected to a 120 V , 60 HZ ac generator, the current of 6.4 A lags the voltage by 30o. What are the two elements and their values? 2. Relevant equations 3. The attempt at a solution given E = 120v, f = 60Hz, i = 6.4A, φ =300 From the problem current lags voltage so this is a circuit containing resistance and inductance inthis circuit , tanφ = ωL/R R = E/i = 120/6.4 = 18.75Ω L = tanφR/ω = tan300*18.75/2*3.14 *60 =0.028 henry Is this reasoning correct?
