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..
.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?
a. Show how you would connect all five capacitors to get a maximum capacitance and find the maximum capacitance in terms of C.
b. Show how you would connect all five capacitors to get a minimum capacitance and find the minimum capacitance in terms of C.
