The figure represents a voltage regulator circuit using a Zener diode. The breakdown voltage of the Zener diode is \(6\,V\) and the load resistance is \(R_L= 4\,k\Omega .\) The series resistance of the circuit is \(R_i = 1\,k\Omega .\) If the battery voltage \(V_B\) varies from \(8\,V\) to \(16\,V,\) what are the minimum and maximum values of the current through Zener diode?
- A \(0.5\,mA;\,\,0.6\,mA\)
- B \(1\,mA;\,\,8.5\,mA\)
- C \(1.5\,mA;\,\,8.5\,mA\)
- D \(0.5\,mA;\,\,8.5\,mA\)
Answer & Solution
Correct Answer
(D) \(0.5\,mA;\,\,8.5\,mA\)
Step-by-step Solution
Detailed explanation
\({{\text{V}}_{{\text{breaddwon }}}} = 6{\text{V}},\) \({{\text{R}}_{\text{L}}} = 4\,{\text{k}}\Omega ,\) \({{\text{R}}_{\text{i}}} = 1{\text{k}}\Omega \) \({{\text{i}}_{\text{L}}} = \frac{6}{4} \times {10^{ - 3}} = \) \(1.5 \times {10^{ - 3}} = 1.5{\text{mA}}\)…
