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.
