What is electrci heater?

Electric heating is a process in which electrical energy is converted directly to heat energy at around 100% efficiency, using rather cheap devices.

To calculate the amount needed to operate the electric heater in 30 days, we use the formula below.

Formula:

  • A = R×30VIt/1000...........Equation 1

Where:

  • A = Amount needed to operate the heater for 30 days
  • V = Voltage
  • I = Current
  • t = Time
  • R = Electric company charge

From the question,

Given:

  • R = 9.2 cents per kWh
  • V = 120 V
  • I = 15 A
  • t = 3 hours

From the question,

Given:

  • A = 3×30×120×15×9.2/1000
  • A = 1490.4 cents

Hence, The amount required to operate the electric heater is 1490.4 cents.
