A zener diode of power rating 2 W is to be used as a voltage regulator. If the zener diode has a breakdown of 10 V and it has to regulate voltage fluctuated between 6 V and 14 V , the value of R s for safe operation should be _____ Ω .

Correct answer

0

Step-by-step solution

For diode P = V i i = P V = 2 10 = 0 . 2   A Now for V s = 14   V Voltage drop across R s = 14 - 10 = 4   V Thus, V = iR s R s = 4 0 . 2 = 20   Ω
