If voltage across zener diode is 6V then find out value of maximum resistance in this condition.

`2kOmega`

`3kOmega`

`5kOmega`

`4kOmega`

Text Solution

Verified by Experts

The correct Answer is:

`i=(30)/(R=1)mA`
`"voltage across 1 "kOmega=(30)/(R+1).1=(30)/(R+1)=v_(2)`
`(30)/(R+1)=6`
`30=6R+6`
`24=6R" "rArr" "R=(24)/(6)=4kOmega`
