The Electrical Energy Calculator allows you to compute the amount of electrical energy consumed based on power and time. This is useful for estimating energy usage in homes and industries.

Electrical Energy Calculator

Inputs

Outputs

EXAMPLE:

  • INPUTS:

    • Voltage (V) : 230 Volts
    • Current (I) : 4 Amperes
    • Time (t) : 2 hours

  • OUTPUT:

    • Power (in Watts) = 920 Watts
    • Power (in Kilowatts) = 0.92 kW
    • Energy (in kWh) = 1.84 kWh
    • Energy (in Joules) = 6,624,000 Joules

Electrical Energy Formula

Electrical Energy Formula

Where,

  • E = Electrical Energy (Joules or kWh)
  • P = Power (Watts)
  • V = Voltage (Volts)
  • I = Current (Amperes)
  • t = Time (seconds or hours)
  • 1 kWh = 3.6 x 10^6 Joules

Key benefits of Using the Electrical Energy Calculator

  • Efficiency : Quickly calculates energy consumption without manual computations.
  • Cost Estimation : Helps estimate electricity costs based on usage.
  • User-Friendly : Simple interface for easy input and output interpretation.
  • Versatility : Applicable for residential and industrial energy calculations.
