Determine the current strength in the spiral of the electric stove, if the voltage is 220V and the resistance is 1100 Ohm.

U = 220 V.

R = 1100 ohms.

I -?

According to Ohm’s law for a section of the circuit, the current I in the spiral of the electric stove is directly proportional to the voltage at its ends and is inversely proportional to the resistance of the spiral R: I = U / R.

I = 220 V / 1100 Ohm = 0.2 A.

This means, how many times the voltage U increases, how many times the current in spiral I.

How many times the resistance of the spiral R increases, so many times the current strength I in it decreases.

Answer: in the spiral of the electric stove, the current strength is I = 0.2 A.
