Answer:

Electric current, I = 4.08 A

Step-by-step explanation:

We have,

Power of vacuum cleaner is 500 W

Resistance of vacuum cleaner is 30 ohms

It is required to find the current flowing through the vacuum cleaner. It can be calculated using the definition of power delivered. Its formula is given by :


P=I^2R

I is electric current


I=\sqrt{(P)/(R)} \\\\I=\sqrt{(500)/(30)} \\\\I=4.08\ A

So, the electric current flowing through the vacuum cleaner is 4.08 A.
