Given:
W = 110 Watt – power of an electric soldering iron;
U = 220 Volts – the voltage for which the electric soldering iron is designed.
It is required to determine I (Ampere) – the current in the winding of an electric soldering iron.
To determine the amperage in the soldering iron, you need to use the following formula:
W = U * I, hence:
I = W / U = 110/220 = 0.5 Ampere.
Answer: the current in the winding of the electric soldering iron is 0.5 Amperes.
