Question

A computer uses 3.5 A at 110 V. What is its resistance in ohms?

Answer 1

31.43 Ω

Step-by-step explanation:

Using Ohm's Law:

`\displaystyle{V=IR}`

Where V = voltage (V) , I = electric current (A) and R = resistance (ohm)

We know that a computer uses 3.5 ampere at 110 volt, we want to know the resistance. Therefore substitute V = 110 and A = 3.5

`\displaystyle{110=3.5R}\\\\\displaystyle{(110)/(3.5)=R}\\\\\displaystyle{R=31.43}`

Therefore, the resistance will be around 31.43 Ohm
