An electric stove operates on a larger 220 V line. How much power is needed to cook a pizza if 0.45 A of current is used.

power = voltage * current

= 220 * .45 Watts

by the way even at 220 volts, .45 amps does not sound like much to cook pizza.

To calculate the power needed to cook a pizza on an electric stove, we can use the formula:

Power (P) = Voltage (V) x Current (I)

Since the stove operates on a larger 220 V line and uses 0.45 A of current, we can substitute these values into the formula:

P = 220 V x 0.45 A

Now, let's calculate the power:

P = 99 W

Therefore, the power needed to cook a pizza on this electric stove is 99 watts.
