[SOLVED] calculate RMS current!?
The maximum potential difference across certain heavy-duty appliances is 240 V. Assume that the total resistance of an appliance is 190 ohms.
(a) Calculate the rms potential difference.
169.68V <--CORRECT
but for
(b) calculate the RMS current,
i have no idea what to do!?
