Basic Concepts of Electricity - Power

What is power?

• The application of a force through a distance

• The rate at which energy is converted from one form to another

• The capacity to do work

• The rate at which electrical energy is transferred by an electric circuit

What is the unit of electrical power?

What is the formula for electrical power?

• Power = Voltage X Current

• Power = Force X Distance

• Power = Energy / Time

• Power = Voltage X Charge

What is the definition of electrical current?

• The rate at which charge is flowing

• The application of a force through a distance

• The capacity to do work

• The rate at which electrical energy is transferred by an electric circuit

What is the formula for electrical resistance?

• Resistance = Voltage / Current

• Resistance = Power / Voltage

• Resistance = Energy / Time

• Resistance = Charge / Voltage

What is the definition of voltage?

• The rate at which energy is converted from one form to another

• The application of a force through a distance

• The potential difference in charge between two points in an electrical field

• The rate at which electrical energy is transferred by an electric circuit
