What s wrong with capacitors having no resistors
My old ceiling fan shows (3 wire) two capacitors: one leg is 1.5 uFD with a 270k ohm resistor, the other leg is 3uFD with a 270k ohm resistor, .5 watt, the voltage is 300v. I can find a replacement 3 wire capacitor with one leg 1.5 uFD, one leg 3uFD, but no resistors are shown.

6.3: Resistors in Series and Parallel
The equivalent resistor of any number of resistors is always higher than the equivalent resistance of the same resistors connected in parallel. The current through for the series circuit would be (I = frac{3.00, V}{5.00, Omega} = 0.60, A), which is lower than the sum of the currents through each resistor in the parallel circuit, (I = 6.00, A).

21.6: DC Circuits Containing Resistors and Capacitors
When there is no current, there is no (IR) drop, and so the voltage on the capacitor must then equal the emf of the voltage source. This can also be explained with Kirchhoff''s second rule (the loop rule), discussed in Kirchhoff''s Rules, which says that the algebraic sum of changes in potential around any closed loop must be zero.

Capacitive Voltage Divider as an AC Voltage Divider
After a period of time equal to about "5RC" or 5 time constants, the plates of the capacitor are fully charged equalling the supply voltage and no further current flows. At this point the reactance of the capacitor to DC current flow is at its maximum in the mega-ohms ...

I don''t really get what is the purpose of the capacitor C1 which is connected in parallel with the feedback resistor. After my knowledge, if we modify the input signal frequency the over all gain will modify accordingly because of the impedance of the capacitor which ...
What is a resistor and a capacitor?
Since the capacitor is basically a charge storage, there is no such equation as this hence you can say there is no electrical resistance. But if you define resistance by its truest meaning, the capacitor is resistant to low frequencies but allows high frequency currents to pass through.
