The resistance of the heating element of the electric kettle is 20 ohms. Determine the power of the current passing through the heating element at 220 V.
These tasks: R (resistance of the heating element) = 20 Ohm; U (operating voltage for the electric kettle) = 220 V.
The power of the kettle heating element is determined by the formula: P = U2 / R.
Calculation: P = 220 ^ 2/20 = 2420 W (2.42 kW).
Answer: The power of the current passing through the heating element of the kettle is 2.42 kW.
