Question

a toaster uses 9.00 a of current when plugged into a 120 v outlet.

how much power is used by the toaster when it is plugged into the outlet?

answer: w

Explanation:

Identify the given values

We are given the following values from the problem statement:

• Current \(I = 9.00\text{ A}\)
• Voltage \(V = 120\text{ V}\)

State the electric power formula

Using the Electrical Devices knowledge point, the electric power \(P\) consumed by an electrical device is calculated using the formula:

$$P = V \times I$$

Calculate the power

Substitute the given values into the formula:

$$P = 120\text{ V} \times 9.00\text{ A}$$

$$P = 1080\text{ W}$$

Express with correct significant digits

The given values are \(9.00\text{ A}\) (three significant digits) and \(120\text{ V}\) (typically treated as three significant digits in this context, or we can write the final value as \(1080\) or \(1.08 \times 10^3\)). The standard numerical value is \(1080\).
