Hi.
Well.. alright, say I want to measure Voltage used by an appliance from the mains of 240V/50Hz.
Various methods where one of them include stepping down the voltage to about 5V and using the PIC to perform calculation and then display it using an external device.
My question is, if the mains offer 240V, won't the reading always be 240V, due to the fact the stepping down is done internally by the appliance (i.e. step down -> convert ACV to DCV)?
