Studdy Solution

STEP 1

1. The voltage (V V ) of the hair dryer is 100 100 volts.
2. The current (I I ) drawn by the hair dryer is 9.0 9.0 amperes.
3. We need to calculate the power (P P ) of the hair dryer using the formula P=VI P = VI .

STEP 2

1. Identify the formula for power.
2. Substitute the given values into the formula.
3. Calculate the power.

STEP 3

Identify the formula for power. The power (P P ) consumed by an electrical device is given by the formula:
P=VI P = VI
where V V is the voltage and I I is the current.

STEP 4

Substitute the given values into the formula. Given V=100 V = 100 volts and I=9.0 I = 9.0 amperes, substitute these values into the power formula:
P=100×9.0 P = 100 \times 9.0

STEP 5

Calculate the power by performing the multiplication:
P=100×9.0=900 P = 100 \times 9.0 = 900
The power of the hair dryer is:
900 watts\boxed{900 \text{ watts}}
