आरेख में दर्शाए अनुसार परिपथ में संयोजित जेनर डायोड \(( V _{ z }=15\; V)\) के सिरों पर शक्तिक्षय का मान \(x \times 10^{-1}\) watt है। \(x\) का मान निकटतम पूर्णांक में \(\dots\) होगा।

  1. A \(5\)
  2. B \(4\)
  3. C \(2\)
  4. D \(6\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(5\)

Step-by-step Solution

Detailed explanation

Voltage across \(R _{ S }=22-15=7 V\) Current through \(R _{ S }= I =\frac{7}{35}=\frac{1}{5} A\) Current through \(90 \Omega= I _{2}=\frac{15}{90}=\frac{1}{6} A\) Current through zener \(=\frac{1}{5}-\frac{1}{6}=\frac{1}{30} A\) Power through zener diode \(P = VI\)…
