On the body of the roaster electric furnace there is an inscription: “220 V, 660 W”. Find the amperage consumed by the roaster.

The power of this roaster is defined as the product of current and voltage. Therefore, to find out the current consumed by the roaster, you need to divide its power by the voltage in the network, equal to 220 volts. What we do:

660/220 = 3 (A).

Answer: The current consumed by this roaster is 3 amperes.
