A capacitor can be charged without a resistor by directly connecting it to a DC voltage source. When the capacitor is connected to the voltage source, current will flow from the source into the capacitor, causing a build-up of charge on the capacitor''s plates. This process will continue until the voltage across the capacitor equals the voltage of the source.

Assuming the capacitor is uncharged, the instant power is applied, the capacitor voltage must be zero. Therefore all of the source voltage drops across the resistor. This creates the initial current, and this current starts to charge the capacitor (the initial rate being equal to (i/C) as dictated by Equation 8.2.6).
Process Of Charging A Capacitor Without A Resistor. To charge a capacitor without a resistor, you will have to use the concept of voltage division. This means that you should connect the resistor and capacitor in parallel to be affected by the same voltage. If done correctly, you can charge a capacitor without a resistor.
