Question
A zener diode with 5 V zener voltage is used to regulate an unregulated dc voltage input of 25 V . For a $400\Omega$ resistor connected in series, the zener current is found to be 4 times load current. The load current $\left( {{I_L}} \right)$ and load resistance $\left( {{R_L}} \right)$ are :
Select the correct option:
A
${I_L} = 0.02mA;{R_L} = 250\Omega $
B
${I_L} = 10mA;{R_L} = 500\Omega $
C
${I_L} = 20mA;{R_L} = 250\Omega $
D
${I_L} = 10A;{R_L} = 0.5\Omega $
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
