Which of the following devices is/are based on heating effect of electric current?

  1. (i) Incandescent lamp
  2. (ii) Electric geyser
  3. (iii) Electric generator

    AAll

    BNone of these

    Ci, ii

    Di only

    Answer:

    C. i, ii

    Read Explanation:

    • Incandescent lamps and electric geysers work on the principle of heating effect of electric current.

    • Anelectric generator does not directly use the heating effect of electric current

    • It converts mechanical energy into electrical energy
