The voltage output of an AC source is given by the expression:-
deltaV=(200V)Sin wt. Find the r.m.s. current in the circuit when the source is connected to a 100ohm resistor.

Vrms = -200/[2^(1/2)] coswt i guess...? since you said delta, it means rate of change...
then Irms = -2/[2^(1/2)] coswt, deltaIrms = 2/[2^(1/2)] sinwt
V = IR; in rms we divide the voltage or the current by 2^(1/2)... hope it helps...hehe

Vrms = sqrt(0.5)*V
Irms = Vrms/R
EDIT: I'm assuming that "deltaV" is simply a voltage. If it were a rate of change of voltage, time would be included in the term, e.g., dV/dt.

Somebody is paying a lot of money for you to get a good education. Stop cheating and go read your expensive textbook!
