Question

A zener diode with **$$5 \, 	ext{V}$$** zener voltage is used to regulate an unregulated dc voltage input of **$$25 \, 	ext{V}$$**.
For a **$$400 \, \Omega$$** resistor connected in series, the zener current is found to be **$$4$$** times load current.
The load current $$I_L$$ and load resistance $$R_L$$ are:

Accepted Answer

D. $$I_L = 10 \, 	ext{mA}; \, R_L = 500 \, \Omega$$

Answer

A. $$I_L = 20 \, 	ext{mA}; \, R_L = 250 \, \Omega$$

Answer

B. $$I_L = 10 \, 	ext{A}; \, R_L = 0.5 \, \Omega$$

Answer

C. $$I_L = 0.02 \, 	ext{mA}; \, R_L = 250 \, \Omega$$
