## Homework Statement

A resistor connected across an AC power supply has a current given by I=(1.35A)cos(300t) when connected to a power supply with emf 120 V rms.

Find the RMS current.

## Homework Equations

I

_{RMS}=I

_{max}/√2

## The Attempt at a Solution

I

_{RMS}=I

_{max}/√2

I

_{RMS}=0.477 A

INCORRECT

Not exactly sure what to do? I am not given any other data besides what i have written above. I do not have the Power, or the Resistance, and in fact will have to solve for those in part B. and C. of this problem. I know I am missing something here, and i have re-read the chapter in my textbook but it is not helping.
