1. The problem statement, all variables and given/known data Calculate the current in the capacitor shown in the figure below if the voltage input is V(t) = 29cos(377t-30) V, C = 1 micro Farad 2. Relevant equations i = C dv/dt 3. The attempt at a solution I essentially differntiate V(t) and multiply by 1 * 10^-6. I then get a negative amplitude, so I add 180 degrees to the phase angle to get a positive amplitude, i = 1*10^-6*29*377 * (-sin(377t - 30) = 0.0109sin(377t + 150) What is the phase angle? The correct answer is 60 degrees. I'm confused about how to get this. I'm getting 150 degrees.
