The Basics of Electricity

Electricity is the flow of electrons through a conductor, such as a wire. The amount of electron flow is measured in amperes, while the voltage is measured in volts. Resistance is the opposition to electron flow, measured in ohms.

Ohm's Law is a fundamental equation that relates these three quantities: Voltage = Current × Resistance. This equation can be used to calculate any of the three quantities if the other two are known.

Electrical Components

HVACR systems use a variety of electrical components, including:

• Transformers: Transformers change the voltage of electricity.
• Capacitors: Capacitors store electrical energy.
• Inductors: Inductors oppose changes in current flow.
• Relays: Relays are used to control the flow of electricity.
• Motors: Motors convert electrical energy into mechanical energy.

Troubleshooting Electrical Systems

Troubleshooting electrical systems can be a challenging task. However, by following a systematic approach, it is possible to identify and resolve most problems.

The first step is to check for power at the electrical panel. If there is no power, check the breakers or fuses. If the breakers or fuses are tripped, reset them. If the breakers or fuses continue to trip, there is likely a short circuit in the system.

Once you have confirmed that there is power at the electrical panel, you can begin to troubleshoot the individual components of the system. Use a multimeter to measure voltage, current, and resistance. Compare your measurements to the manufacturer's specifications to identify any problems.

Electrical theory is essential for HVACR professionals. By understanding the basics of electricity and the different electrical components used in HVACR systems, you can troubleshoot, repair, and maintain electrical systems with confidence.
