The current through the coffee machine is 3.48 A.

To calculate the current flowing through the coffee machine, we use the formula below.

Formula:

  • E = VIt............. Equation 1

Where:

  • E = Energy transfered by the machine
  • V = Voltage of the main supply
  • I = current through the coffee,
  • t = time.

Make I the subject of the equation.

  • I = E/Vt.............. Equation 2

From the question,

Given:

  • E = 12 kJ = 12000 J
  • V = 230 V
  • t = 15 seconds.

Substitute these values into equation 2

  • I = (12000)/(230×15)
  • I = 3.48 A.

Hence, The current through the coffee machine is 3.48 A.
