If the load resistance decreases in a zener regulator, the zener current

zener diode special purpose diodes electronic devices semiconductor electronics: materials, devices and simple circuits physics

  1. Decreases

  2. Stays the same

  3. Increases

  4. Equals the source voltage divided by the series resistance

Show answer
Correct Option: C
Explanation:

The load current is given by $I _L=\dfrac{V _z}{R _L}$ and the zener current is given by $I _z=I _s-I _L$. Thus, if the load resistance decreases, load current increases. This in turn will reduce the zener currentÂ
