Question

In a zener Regulator, zener diode is rated as 10 v, 1 watt .The unregulated voltage

supplied is 50v.The load resistance varies from 1KΩ to 5KΩ and a series resistor of

400Ωis connected. Find minimum and maximum zener current. Also find the change in
zener current.
​

Answer 1

Answer:

1. Voltage drop across Rs is

Voltage drop across Rs is(10−5)=5V

Voltage drop across Rs is(10−5)=5V∴I=RsV=2005=0.025A

Voltage drop across Rs is(10−5)=5V∴I=RsV=2005=0.025A=25mA.

2.The unregulated voltage supplied is 50v. The load resistance varies from 1KΩ to 5KΩ and a series resistor of. 400Ωis connected.

sorry mujhe last vale ka samje nahi Aya

but I hope it's help you
