This is not correct. Relay is an inductiv load. The characteristic of inductor is also resistance (X=2*pi*f*L). There is no need for extra resistor. You just need to know resistance of relays inductor to calculate current (U=R*I) to properlly calculate resistor on base of transistor. With resistor o...
