Resistance of electric soldering iron 440 0m. It works at 220 V. Determine the power consumed by the soldering iron.
| February 23, 2021 | education
These tasks: R (resistance of the considered electric soldering iron) = 440 Ohm; U (voltage at which the soldering iron works) = 220 V.
The power consumed by the considered electric soldering iron is determined by the formula: P = U ^ 2 / R.
Calculation: P = 220 ^ 2/440 = 110 W.
Answer: The electric soldering iron consumes 110 watts.
