Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is electrical resistance and why does it happen?Resistance is how much a material slows down electrons. It happens when electrons bump into vibrating atoms or impurities, making it harder for electricity to flow.
2. What is conductance and how is it related to resistance?Conductance is the opposite of resistance. It shows how easily electricity can move through a material. Conductance equals 1 divided by resistance.

Ohm's Law: A fundamental relationship stating that current is directly proportional to voltage and inversely proportional to resistance.
Resistivity: A material's inherent ability to oppose the flow of electric current, independent of its shape or size.
Conductivity: A material's inherent ability to conduct electric current, being the inverse of resistivity.
