Average power factor values for the most commonly-used equipment and appliances

Here are some average power factor values for commonly used equipment and appliances:

1. Incandescent Lamps: Power factor is typically close to 1.0 for incandescent lamps since they are purely resistive loads.

2. Induction Motors: Power factor for induction motors varies depending on the motor's size, design, and load conditions. It typically ranges from 0.7 to 0.9, but it can be lower under light loads.

3. Synchronous Motors: Synchronous motors can have power factors close to unity (1.0), especially when operating under full load and with power factor correction capacitors.

4. Fluorescent Lamps and Ballasts: Power factor for fluorescent lamps and their associated ballasts can vary but is generally around 0.9.

5. Air Conditioners: Power factor for air conditioners can vary but is typically around 0.9.

6. Refrigerators: Power factor for refrigerators can vary but is generally around 0.8 to 0.9.

7. Computers and Electronics: Power factor for computers and electronic devices can vary widely depending on the design and efficiency of their power supplies. It can range from 0.5 to 0.9 or higher.

8. Power Tools: Power factor for power tools can vary depending on the type and design but is generally around 0.8 to 0.9.

These are average values, and actual power factor values can vary depending on factors such as the specific model, design, and operating conditions of the equipment or appliance. It's important to note that power factor can also be improved through the use of power factor correction techniques such as capacitors, which can bring the power factor closer to unity (1.0) and improve overall system efficiency.
