Question

In a bulb, electrical energy is converted into:

• A. Light energy only
• B. Mechanical energy only
• C. Both heat and light energy
• D. Heat energy only

Answer 1

The correct option is C

Both heat and light energy

When electric current flows through the filament made up of tungsten, it heats up, emitting visible light. Hence, in a bulb, electrical energy is converted into both heat and light energy.
