A Zener diode is connected to a battery ...

A Zener diode is connected to a battery and a load as shown below. The currents `l, l_(Z)` and `l_(L)` are respectively :-

A

12.5 mA, 5 mA, 7.5 mA

B

15 mA, 7.5 mA, 7.5 mA

C

12.5 mA, 7.5 mA, 5 mA

D

15 mA, 5 mA, 10 mA

Text Solution

Verified by Experts

The correct Answer is:
C
`I_(L)=(V_(2))/(R_(L))=(10)/(2)mA=5mA`
`I=(60-10)/(4)mA = 12.5 mA`
`therefore I_(Z)=I-I_(L)`
`= 12.5 - 5=7.5 mA`
