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 the SI unit of electric potential?The volt (V) is the standard measure for electrical potential difference
2. What is a volt and why is it important?A volt is the unit that measures how much electrical "push" there is between two points. It tells us how much work can be done on an electric charge. This push is what makes electric current flow.
3. Who was Alessandro Volta and why is the volt named after him?Alessandro Volta was an Italian scientist who lived in the 1700s and 1800s. He invented the first steady source of electricity, the voltaic pile, in 1800. The unit of voltage was named after him to honor his discovery.

Electric Potential Difference: The work done per unit charge to move a charge between two points in an electric field.
Electromotive Force (EMF): The total energy per unit charge supplied by an energy source, like a battery.
Ohm's Law: A fundamental law stating that voltage (V) equals current (I) multiplied by resistance (R): V = IR.
