- At 0-, no currrent flows through the capacitors because they are open, how did you combine the capacitors for the voltage divider since it is the capacitance value and not reactance, is it right? Can we just combine the capacitance value? Please explain. I did not understand..arrow_forward3 Determine the current through the capacitor just before and just after the switch is closed in Figure P5.23. Assume steady-state conditions for t < 0. C = 0.5 µF V = 12 V R = 0.68 k2 R2 = 1.8 k2 t= 0 R2arrow_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_forwardB Determine the voltage across the inductor just before and just after the switch is changed in Figure P5.38. Assume steady-state conditions exist for t < 0.

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
