What is value of current I in given circuit
Options
- A6 m A
- B10 m A
- C4 m A
- Dzero
Correct answer
C. 4 m A
Step-by-step solution
The potential difference across the Zener diode and the resistance R 2 is the same because they are in parallel connection. V z = V 2 = 6 V Let the potential difference across R 1 is V 1 , then 16 = V 1 + 6 V 1 = 10 V I 1 R 1 = 10 I 1 = 10 1000 = 0.01 A I 2 R 2 = 6 V I 2 = 6 1000 = 0 . 006 A I = 0 . 01 - 0 . 006 = 0 . 004 A = 4 mA
