Calculate the value of current through a 155 µF capacitor at time t = 1 sec. Vc (t) is the the voltage across the capacitor: Vc = 40cos(28t + 74°) V Assume that the capacitor is initially discharged. Remember that the frequency is in rad/s (Round off to two decimal places.) Find the phasor representation of V(t) = 9sin(183t+ -43%) and put the phase angle (in degrees) as your answer. Note that it is showing sin. Find the phasor form of I(t) = 2sin(181t+85°) + 13cos(181t+ -56%) and put its magnitude as your answer. (Round off to two decimal places.). The equation above is the real value of the current.
