Question

Which energy is transformed to which energy in an electric motor? Why in domestic circuits, electric bulbs, electric fans, refrigerators etc., are connected in parallel combination ? [1 + 2]

WBBSE Class X Physical Science Current Electricity 03 Mark 2022

Answer

In an electric motor, electrical energy is transformed into mechanical energy.

Domestic Circuits Use Parallel Combination because

  1. Each appliance gets the same voltage, ensuring it works properly.
  2. If one appliance fails, others still work. This prevents disruptions.
  3. Each appliance has its own switch allowing for easy operation of each appliance.
