Question

Question.
The electrical resistance of a circuit is influenced by three primary factors.

Possible Answers.
1. conductivity
2. shape
3. insulator
4. diameter
5. length

Answer 1

okay resistance is just a measure of how easily the atoms in a material allow electrons to pass through that material.
When electrons pass through a material, they bump into the atoms in the material. The greater the bumping, the greater the resistance.

Coming to the question, conductivity is just the opposite of resistance. i.e. greater the conductivity, the easier it is for electrons to pass though the material.

Length is also a factor that influences resistance because
greater the length--->greater the resistance because the electrons have to pass through more material. It's like its harder to swim 500 meters than say 100 meters.

The third major factor is the diameter. The greater the diameter, the lesser the resistance.

Answer 2

So diameter, length, and... conductivity?

yup

Answer 5

ok thank you! :)

Answer 6

you're welcome :)

Answer 7

diameter, length and conductivity
\[R=\frac{ \rho L }{ A }\]
