What's the current in my circuit?

I constructed a DC-AC inversion circuit. The output is 5 Vrms, 7 Vpeak, and 60 Hz with an RC load "R = 2 ohms and C = 100nF). I want to know the current the load can get. How do you calculate the current?

Thanks

Irms = 5V/2 ohms + 5V/ Xc
where Xc = 1/(2Pi F C)

There is a phase shift in there, but at 188.5 ua in the capacitor, it won't be much compared to the 2.5 amps through the resistance.
