The electric soldering iron is designed for a voltage of 220 V and a current strength of 0.2 A. Calculate the current power in the soldering iron …

Since the electrical power of an electric soldering iron, which is released in the section of the electrical circuit, will be equal to the product of the voltage in the network and the current strength, then: P = U * I, where U = 220 V, I = 0.2 A.
Let’s calculate:
P = U * I = 220 * 0.2 = 44 W.
Check: W = B * A = W.
Answer. The current power in the soldering iron is 44 W.
