The voltage at the terminals of the electric iron is 220 volts, the resistance of the heating element of the iron is 50 ohms, which is equal to the current in the heating element.
According to Ohm’s law, the current in the heating element of the iron will be directly proportional to the voltage at the terminals of the iron and inversely proportional to the resistance of the heating element.
I = U / R, where I is the current in the heating element (A), U is the voltage at the terminals (U = 220 V), R is the resistance of the heating element (R = 50 Ohm).
Let’s calculate the current in the heating element of the iron:
I = U / R = 220/50 = 4.4 A.
Answer: The current in the heating element of an electric iron is 4.4 A.
