The electric iron is plugged into a 220V network. What is the current in the heating element of the iron if the resistance is 48.4 ohms?
Initial data: U (voltage in the network to which the iron is connected) = 220 V; R (electric iron resistance) = 48.4 ohms.
To determine the current in the heating element of the iron, it is necessary to divide the voltage in the network by the resistance of the iron itself (Ohm’s law for a section of the circuit): I = U / R.
Let’s calculate: I = 220 / 48.4 ≈ 4.56 A.
Answer: The current in the heating element of the iron is 4.56 A.
