Electricity Load Calculator

(Electricity Load Calculator)

Electricity Load Calculator is a tool designed to help users determine the electrical load in kilowatts (kW) for a given voltage, current, and power factor. It’s particularly useful for engineers, electricians, and individuals working with electrical systems to understand and manage power consumption effectively.

Formula: The calculation for electricity load (P) is derived from the formula: P = VIcos(θ) / 1000


  • P is the power in kilowatts (kW)
  • V is the voltage in volts (V)
  • I is the current in amperes (A)
  • θ is the angle of the power factor (cosine of the phase angle between voltage and current)

How to Use:

  1. Input the voltage (V), current (A), and power factor into their respective fields.
  2. Click the “Calculate” button.
  3. The result will display the electricity load in kilowatts (kW).

Example: Suppose you have a system with a voltage of 220V, a current of 10A, and a power factor of 0.85.

  1. Enter 220 in the Voltage field.
  2. Enter 10 in the Current field.
  3. Enter 0.85 in the Power Factor field.
  4. Click the “Calculate” button.
  5. The result will show the electricity load, which might be around 1.87 kW.


Q: What is electricity load? A: Electricity load refers to the amount of power consumed by electrical equipment or systems.

Q: Why is power factor important? A: Power factor indicates the efficiency of electrical power usage. A higher power factor signifies better utilization of electrical power.

Q: Can I use this calculator for DC circuits? A: No, this calculator is specifically designed for AC circuits.

Q: What happens if the power factor is 1? A: A power factor of 1 indicates that the voltage and current are in phase, resulting in maximum power transfer efficiency.

Q: Is power factor always a decimal? A: Yes, power factor is represented as a decimal between 0 and 1.

Q: How can I improve power factor? A: Power factor can be improved by using power factor correction devices or optimizing the electrical system’s design.

Q: What is the unit of electricity load? A: Electricity load is typically measured in kilowatts (kW) or megawatts (MW).

Q: Can this calculator handle three-phase systems? A: No, this calculator is designed for single-phase systems.

Conclusion: The Electricity Load Calculator provides a convenient way to determine electrical load based on voltage, current, and power factor inputs. By accurately estimating electricity load, users can make informed decisions regarding energy consumption and system design.
