Question

an electrical appliance draws 9.0 amperes of current when connected to a 120 - volt source of potential difference. what is the total amount of power dissipated

Explanation:

Step1: Recall the power formula

The formula for power \( P \) in an electrical circuit is \( P = VI \), where \( V \) is the voltage and \( I \) is the current.

Step2: Substitute the given values

Given \( V = 120\space V \) and \( I = 9.0\space A \). Substitute into the formula: \( P=(120)(9.0) \).

Step3: Calculate the power

\( P = 120\times9.0=1080\approx1100\space W \) (rounded to two significant - figures as per the options).

Answer:

1100 W
