Power is the rate at which work is done or energy is transferred. A power plant converts fuel into electrical energy.

• Power is measured in watts or kilowatts.

• A power plant works by converting fuel into heat, which is then used to generate steam to turn a turbine and produce electricity.

• There are different types of power plants such as coal-fired, nuclear, hydroelectric, and renewable energy plants.

• Power factor is the ra...read more

The power triangle is a graphical representation of the relationship between real power, reactive power, and apparent power in an AC circuit.

• Real power is represented by the horizontal leg of the triangle.

• Reactive power is represented by the vertical leg of the triangle.

• Apparent power is represented by the hypotenuse of the triangle.

• The angle between the horizontal leg and the hypotenuse is the power factor angle.

• The p...read more

Phase angle is the difference in phase between two waveforms.

• Phase angle is measured in degrees or radians.

• It is used to describe the relationship between two waveforms.

• It is important in fields such as electrical engineering and physics.

• For example, in AC circuits, the phase angle between voltage and current determines the power factor.

Calculate total power consumption given a problem

• Determine the power consumption of each device

• Add up the power consumption of all devices

• Consider the time period over which power is consumed

• Account for any inefficiencies or losses in the system
