This asks:if the value of the source resistor in fig 3 was reduced, describe the effect this would have on the drain voltage and the source voltage of the circuit.

the reply i received said that the biasing voltage Vgs would be effected. But i was under the impression that this voltage was zero, as it is negative w.r.t. the source voltage which is positive.

so, i am asking you if the resistance of Rs is reduced, would the biasing voltage Vgs be reduced also?

what about the drain voltage Vd, would this be reduced also?

and the source voltage, Vs. the formula to get this is Vs=IdRs, so how can this be reduced by the resistance?

So, basically, i am asking you to be more specific with your answer.

watt's what!

excuse me if i seem ignorant, but i am returning to studies after nearly 20 years on the tools, so i have a bit of trouble getting around electronic circuitry. i am electrician by trade.
