Hello guys. I am currently studying about ways to drive DC motors. I came across Thyristor and have been looking in to them for a while. I am a little confused about the resistor choises to limit the current to the gate.

Lets analyse this circuit. How do I know what value of Rg and Rgk to pick. Lets say i need 10 mA of current to flow into the gate of thyristor and the supply is 9v. I can determine what current would flow through Rg but I cannot determine what current will flow to Rgk and gate. The current that was flowing to Rg will be split to Rgk current and Gate current but as we do not know internal resistance of Gate we cannot calculate the current that will be flowing to the gate. I might have confused everything but thats what I am confused about..
