| **Determine the resistance of the spiral R of the electric stove, if, when you turn on its network with a voltage of U = 220 V, it consumes 1 kW of power.**

As we know from the school physics course, resistance can be calculated using the following formula:

R = U ^ 2 / P, where U is the voltage in a particular network, and P is, respectively, the power consumption.

Let’s determine what the resistance of the spiral of a conventional electric stove will equal, when from the condition of our problem we know for sure that it is connected to a network with a voltage of 220 V, and consumes 1 kW at the same time:

1 kW = 1000 W;

220 * 220: 1000 = 48.4.

Answer: The resistance of the coil is 48.4 ohms.
