A resistor of resistance R is connected to an AC

generator with EMF(t)=(EMF_max)sin((w_d)t). (a) Write

Kirchhoff's Loop Rule for this circuit at a particular

instant of time. Is your result a differential equation?

(b) Find the current as a function of time. Now assume

R=50 Ohm and EMF_max = 30.0 V. (c) What is the amplitude

of the resulting alternating current if the frequency of

the EMF is 1.00 kHz?

2. Relevant equations

V_R = R dQ(t)/dt

3. The attempt at a solution

Ok, so the differential equation I came up with is:

V_G + V_R = 0

E_m sin(w_d t) = R dQ(t)/dt

assuming thats correct how do I find the current as a function of time? Replace dq/dt with i? And after that?
