4. a. The voltage across a 5 resistor is v-30 sin(377t + 20°). Find the sinusoidal expression for the current. b. The current through a. 0.1 H coil is i=5 x 106 sin(400t -20°). What is the sinusoidal expression for the voltage? c. The voltage across a 1 μF capacitor is v=-120 sin(374t - 30°). What is the sinusoidal expression for the current? 12asin(374+ 180° -30°) 120 Sin (314 4+1 50°)
