- .A series RLC circuit contains a 4-kN resistor, an inductor with an inductive reactance (X,) of 3.5 kn, and a capacitor with a capacitive reactance (Xc) of 2.4 kN. A 120-Vac, 60-Hz power source is connected to the circuit. How much voltage is dropped across the inductor?arrow_forward=7 Determine the current through the capacitor just before and just after the switch is closed in Figure P5.37.

- The following figure represents an RC-Circuit with the switch. In Figure A, the capacitor is initially uncharged. In Figure B, the capacitor is initially fully charged. 1) Draw and label the current direction immediately after the switch is closed for each figure. 2) Consider Figure A. What is the voltage across the capacitor as t → 0? Explain. 3) Consider Figure B. Is the voltage across the resistor increasing, decreasing or staying the same as t → 0? Explain. A) B) R Carrow_forwardA capacitor "C", an inductor "L" and a switch "S" are connected in series. When the switch is open, the plate to the left of the capacitor has charge "Qo". The switch is closed the load and current vary sinusoidally with time. Represent graphically the load "Qo" and the intensity of current "I" as a function of time "t", and explain why the current leads the load by a phase difference of 90°.arrow_forward• Circuit diagram needed.• Answer must includecorrect units.arrow_forward
