A resistor and capacitor are connected in series across an AC generator. The emf of the generator is given by v(t) = V cosast, where Vo = 128 V,0= 126 rad/s, R = 410 0, and C = 1.1 JF. (a) What is the impedance of the circuit (in )? 740 106 (6) What is the amplitude of the current through the resistor (In A)? 0172 (©) Write an expression for the current through the resistor. (Use the following as necessary: t. Assume i() is in amps and t is in seconds. Do not include units in your answer.) (+) - 0.172 cos(126rt + 56.75) X (d) Write expressions representing the voltages across the resistor and across the capacitor. (Use the following as necessary: t. Assume v(t) is in volts and is in seconds. Do not include units in your answers.) 70,52 cos(126rt + 56.35) VRCC) vc(0) 105.98 cos( 126xt + 56.35)
