Which energy is necessary for a lamp to glow?

Explanation:
The lamp glows because it uses electrical energy. A lamp is designed to take electrical energy from a power outlet or a battery and convert it into light energy (with some energy becoming heat). Light energy is the output you see, not the input that powers the lamp. If a battery is used, its chemical energy is first transformed into electrical energy, which then powers the lamp. Heat energy is produced as a byproduct of the conversion, not the energy that makes the lamp glow.
