Answer:
When the electric iron is connected to a 110 Volts supply, I = V / R = 110 / 64.7 = 1.7 Amp. Alternately, As the voltage becomes half of its value, the current becomes half of its value, as the current is directly proportional to the potential difference across a conductor or a resistor. This is as per Ohm's law.
