3. + -11 points SerPSE 10 32.5 OP.010. A sinusoidal voltage Av = 37.5 sin(100t), where Av is in volts and t is in seconds, is applied to a series RLC circuit with L = 150 ml, C = 99.0 pF, and R = 55.0 2. (a) What is the impedance in 2) of the circuit? (b) What is the maximum current in A)? (C) Determine the numerical value for win rad/s) in the equation i = I may sin(wt - 0). rad/s (d) Determine the numerical value for • (in rad) in the equation i = Imax sin(wt - ). rad (e) What If? For what value of the inductance (in H) in the circuit would the current lag the voltage by the same angle as that found in part (d)? Н (f) What would be the maximum current (in A) in the circuit in this case?
