Help me find the value or R1 to guareantee that the zener diode will operate in its zener region for the full range of load resistor, RL.
Zener= 6v
Iz= 10 mA minimun
RL can vary from 470 ohms-open circuit

 

Show as your attempt to the problem

 

His exam has ended now, and his teacher probably confiscated his i-phone anyway.

 

As jony130 has indicated, we need you to provide us with a genuine attempt at solving the problem on yoru own prior to our assitance. By showing us how you would tackle the problem, we can then assess where you are weak in your understanding of the solution to the problem.

hi,

this is a zener diode circuit analysis.
