Answer:

The power rate of an electrical device can be calculated using the formula:

\[ \text{Power} (P) = \text{Voltage} (V) \times \text{Current} (I) \]

Given:

- Voltage (V) = 110 volts

- Current (I) = 10 amps

Substituting these values into the formula:

\[ P = 110 \, \text{V} \times 10 \, \text{A} \]

\[ P = 1100 \, \text{W} \]

So, the power rate of the hair dryer is 1100 watts (or 1.1 kilowatts).
