a hair dryer uses 1100 w of power when connected to a 110 v outlet. how much current flows through the hair dryer? (unit = a)
Answer
Explanation:
Step1: Recall power - current - voltage formula
The power formula is $P = VI$, where $P$ is power, $V$ is voltage and $I$ is current. We need to solve for $I$.
Step2: Rearrange the formula for current
Rearranging $P = VI$ gives $I=\frac{P}{V}$.
Step3: Substitute given values
Given $P = 1100\ W$ and $V = 110\ V$, then $I=\frac{1100}{110}$.
Step4: Calculate the current
$I = 10\ A$.
