SCR Question


Recommended Posts

Hey I'm a  ;Dtech student in need of some help.

A 34V dc supply is applied to an SCR in series with a resistor, R.  When the SCR is turned on, its Ih= 6mA, and V a-k= 0.7 V.  What is the minimum value of R before the SCR can turn off?

Rmin=_______ohms  rounded to the nearest hole number.

Do I just divided 34V by 0.006 Amps  or would that be the Max value...

Confused???  Any help would be great...
