A signal line diagram is a graphical representation of a system's electrical circuitry.

• It shows the flow of electrical signals through the system

• It includes symbols for components such as switches, transformers, and relays

• It is used by technicians to troubleshoot and repair electrical systems

• It can also be used to design new systems or modify existing ones

Power factor can be found by dividing the real power by the apparent power.

• Real power is measured in watts (W)

• Apparent power is measured in volt-amperes (VA)

• Power factor ranges from 0 to 1, with 1 being ideal

• Power factor can be improved by using capacitors or correcting the phase angle
