Capicitor Questions

The diagram below shows a circuit diagram of a capacitor discharging through a resistor.

A simple mathematical model of the discharge of the capacitor is shown in the block diagram below. It is assumed that the current I is constant over each small time interval Δt. The process is repeated as shown.

Complete the table for the discharge of the 4700μF capacitor. The small time interval used is Δt = 2.0 s.
