Question

A 350-watt vacuum is plugged into a 120-volt outlet and used for 30 seconds. How much current runs through the vacuum?

2.9 amps
4.0 amps
11.6 amps
42,000 amps

Answer 1

the correct answer is 2.9 becoz .
p=vi

Answer 2

Answer: (a). 2.9 amps current runs through the vacuum

Explanation:

Given that,

Power P = 350 W

Voltage V -= 120 Volt

Time = 30 sec

We know that,

The power is the product of the voltage and current.

$P = V\times I$

$I = \dfrac{P}{V}$

$I = \dfrac{350 \ W}{120\ Volt}$

$I = 2.9 \ amps$

Hence, 2.9 amps current runs through the vacuum.
