Questions
A 10 V Zener diode along with a series resistance is connected across 40 V supply. Calculate the minimum value of the resistance regulated, if the maximum Zener current is 500 mA.
detailed solution
Correct option is B
Vi/p=40V, iz=500mA=500×10−3A=0.5A, Vz=10V , Rs=?If iz is max iL is zero i=iz+iL=0.5+0=0.5AAlso, i=Vi−VzRs ⇒Rs=Vi−Vzi ⇒Rs=40−100.5=300.5=3012=60ΩTalk to our academic expert!
