MCQ
When electric current flows through a conductor, some amount of:
  • ✓
    Electrical energy is converted into heat energy.
  • B
    Electrical energy is converted into mechanical energy.
  • C
    Mechanical energy is converted into electrical energy.
  • D
    Heat energy is converted into electrical energy.
✓

Answer

Correct option: A.
Electrical energy is converted into heat energy.
A conductor allows the flow of electrons through itself that produces electric current.
But conductors also resist the flow of electrons to some extent.
When electron flow is restricted, some of the energy of electrons is converted to heat energy instead of electrical energy.
