Answer: 219 Ohms, C

Explanation:

To find the resistance, you can use Ohm's Law:

V = IR

Where V is the voltage, I is the current, and R is the resistance.

9.2 = 0.042R\\\\\frac{9.2}{0.042} = R

Solving for R gives us around 219 Ω.

What factors affect the strength of the electric force between two objects
Nady [450]
There are three factors:

The charge of the two objects. The electric force is proporcional to the product of the charges of both objects.

The distance that separetes them. The electric force is proportional to the inverse of the squared distance that separates the objects.

The media. The electric force constant of proportionality depends on the media: air, water, oil, glass.

choli [55]

A device that detects small current differences and prevents electrocution that is often required as a safety measure for bathroom, kitchen, and exterior outlets is referred to as: Ground-fault interrupter.

<h3>What are arc-fault circuit interrupter?</h3>

According to "Article 100 Arc-Fault Circuit interrupter (AFCI)," arc-fault circuit interrupter is an electrical device which is designed and developed to deenergize the electrical circuit whenever it detects and recognizes characteristics unique to arcing.

Similarly, a ground-fault interrupter simply refers to an electrical device that is designed and developed for the detection of small current differences in an electrical circuit.

The main purpose of a ground-fault interrupter is to prevent electrocution or electrical shock and as such, it is an important safety measure for the following areas in a building:

  • Bathroom
  • Kitchen
  • Exterior outlets
