4. What is the current flows through a vacuum cleaner if it has a power of 425W and a resistance of 124? Give your answer to two significant figures.​



Answer :

The Electric current, I = 1.84 A    

Given,

Power of vacuum cleaner is 425 W

Resistance of vacuum cleaner is 124 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 = I²R

I is electric current

I = √(P/R)

I = √(425/124)

I = √(3.4) = 1.84

I = Current = 1.84 Ampere

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