(d) At time $t = 0$ i.e. when capacitor is charging, current $i = \frac{2}{{1000}} = 2\,mA$
When capacitor is full charged, no current will pass through it, hence current through the circuit $i = \frac{2}{{2000}} = 1\,mA$
When capacitor is full charged, no current will pass through it, hence current through the circuit $i = \frac{2}{{2000}} = 1\,mA$
