Question

Calculate the wattage of an electric heater which draws 5 ampere current when connected to a 220 volt power supply

Answer 1

Answer: Power = VI

          = 220 × 5  = 1100 watt

          = 1.1 kw

Answer 2

Answer:

Power drawn by electric heater is 1100 W.

Explanation:

• The speed at which energy is converted into an electrical circuit or used to produce work is known as electric power. It is a way to quantify how much energy is consumed over a certain period of time.
  $P=VI$
• Here it is given that I = 5A and V = 220V
  $P=VI\\P=5*220\\P=1100W$
• Hence power drawn by heater is 1100 W.
