Asked by AAA
An AC generator delivers an alternating current
I(t) = (3.4 A) sin[(140π rad/s)t]
to a single resistor in series with the generator.
(a) What is the rms value of the current in the circuit?
(b) If the resistor has a resistance of 240.0 Ω, what is the rms value of the source emf?
(c) What is the maximum value of the source emf?
(d) Write a function that describes the source emf as a function of time. (Use the following as necessary: t. Do not use other variables, substitute numeric values. Assume that e m f is in volts and t is in seconds. Do not include units in your answer.)

This is pretty simple stuff. I will be happy to critique your work.

I can't. Need to know the formula first. Do you know the formulas?
