Circuit Measurements:Circuit Measurements:

• The potential energy per unit of electric charge is The potential energy per unit of electric charge is called called electrical potential. electrical potential.

• The difference in electrical potential between two The difference in electrical potential between two places is called the places is called the potential difference.potential difference. This is also This is also known as known as Voltage.Voltage.

• Voltage causes current to flow through an electric Voltage causes current to flow through an electric circuit.circuit.

• An increase in voltage causes greater flow of electric An increase in voltage causes greater flow of electric current.current.

• The greater the resistance, the less current there is for The greater the resistance, the less current there is for a given voltage.a given voltage.
