Electricity can produce what kind of effects?

  1. Magnetic

  2. Chemical

  3. Sound

  4. Light

The correct answer is: Chemical

Electricity cannot produce Sound effects because sound is produced by vibrations or movement of air molecules, not by electricity. Electricity can produce Magnetic, Chemical, and Light effects because electricity can produce magnetic fields, release energy in chemical reactions, and excite particles to produce light. However, out of these three options, only Chemical effects are directly produced by electricity itself without involving any other mechanisms.
