Question

A charged capacitor with a capacitance of C = 4.00×10-3 F, has an initial potential of 5.00 V. The capacitor is discharged by connecting a resistance R between its terminals. The graph below shows the potential across the capacitor as a funtion of t, the time elapsed since the connection.

Answer 1

Calculate the value of R. Note that the curve passes through an intersection point.

Answer 2

it appears that the capacitor discharged down from 5 volts to 2 volts in 4 seconds
