This is what i have so far the knowns(adsbygoogle = window.adsbygoogle || []).push({});

Vs= 50v

Vz = 10 v

Iz = 32mA

R1 = 1K ohm

Rl =? "potentmeter"

i just got the multisim program and could draw the cir if need be

R1 is in series with the source and the zener and rl are in parallel

it wants me to determine the range of Rl, Il, Vrl

I havew so far is 50 /1K = 50mA

Vrl = 10 v

I l = 50mA-32 mA = 18 mA

Rl = 556 ohms

is this correct and how would i go about finding the range of Rl

thanks joe
