## Main Question or Discussion Point

Please help me with this question. Thanks...

i read from book that in order to charge an uncharged capacitor, we have to connect the capacitor and a resistor with high resistance in series to a battery with emf E. I don't understand what is the use and the effect of the resistor in this charging process? I know that the time constant is given by the product of capacitance and resistance. But is it possible to charge the capacitor without the resistor?
