1. The problem statement, all variables and given/known data 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. 2. Relevant equations IRMS=Imax/√2 3. The attempt at a solution IRMS=Imax/√2 IRMS=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.
