Transformer of a small electrical device takes an AC voltage of 220 voltage of 220 V as its input and supp;ies 12.0Vtto the device. The primary winding of the transformer has 3300 turns .When the device is operatnig it consumes 5.0 W.What is the current taken from the 220 line? Voltage are in RMS value.
