In the circuit shown, the breakdown voltage and the maximum current of the Zener diode are $20\:V$ and $60\:mA$, respectively. The values of $R_{1}$ and $R_{L}$ are $200\: \Omega$ and $1\:k\Omega,$ respectively. What is the range of $V_{i}$ that will maintain the Zener diode in the ‘on’ state?

1. $22\: V$ to $34\: V$
2. $24\: V$ to $36\: V$
3. $18\: V$ to $24\: V$
4. $20\: V$ to $28\: V$
