What is charge?

• Charge is a type of criminal record

• Electric charge is a fundamental property of matter that can be positive or negative.

• Charge is a unit of measurement for electricity

• Charge is a type of credit card

What is resistance?

• The force of gravity on an object

What is Ohm's law?

• Ohm's law states that the current through a conductor is inversely proportional to the voltage across the two points.

• Ohm's law is only applicable to AC circuits, not DC circuits.

• Ohm's law states that the resistance of a conductor is not affected by the voltage across it.

• Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

What is Kirchhoff's voltage law?

• Kirchhoff's voltage law states that the total current entering a junction is equal to the total current leaving the junction.

• Kirchhoff's voltage law is only applicable to DC circuits, not AC circuits.

• Kirchhoff's voltage law states that the total voltage around a closed loop in a circuit is equal to the sum of the voltage drops.

• Kirchhoff's voltage law states that the resistance of a conductor is not affected by the voltage across it.
