Whose resistance is twice that of the original resistor, Physics

Assignment Help:

Regard as a capacitor which is charged to 12 volts and then connected across a resistor. Allow t1/2 be the time it takes for the voltage to drop down to 6 volts. Presume the experiment is repeated but with a resistor whose resistance is twice that of the original resistor. How does the new t1/2 evaluate with the original t1/2?
