A  $\text{P-N}$ junction series with a $100$ ohms resistor, is forward based so that a current of $100 \mathrm{~mA}$ flows. it the voltage across this combination is instantaneously reversed to $10 \mathrm{~V}$ at $t=0$, the reverse current that flows through the diode at $t=0$ is approximately given by

1. $0 \mathrm{~mA}$
2. $100 \mathrm{~mA}$
3. $200 \mathrm{~mA}$
4. $50 \mathrm{~mA}$
