Answer:

12 A

Explanation:

Given,

Power of electric kettle=2.2 kW=2200W (since 1kW=1000W)

Voltage=180V

Current=?

Power = Voltage*Current

Current = Power ÷ Voltage

=2200W ÷ 180V

=12.22 Ampere

=12 A

The amount of current moving through the electric kettle with the given power and voltage is 12A.

Given the data in the question;

  • Power; [tex]p = 2.2kW = 2200W[/tex]
  • Voltage; [tex]V = 180V[/tex]

Using the the power law equation:

Electrical power is the product of voltage and current:

[tex]P = V * I[/tex]

Where V is voltage and I is current

We substitute our given values into the equation

[tex]2200W = 180V * I\\\\I = \frac{2200W}{180V} \\\\I = 12.22A\\\\I =12A[/tex]

Therefore, the amount of current moving through the electric kettle with the given power and voltage is 12A.
