When electric current flows through the metal filament of a light bulb, electrical energy is converted
a.
Heat energy only
b. Heat and light energy
c. Light and motion energy
d. Light energy only



Answer :

When electric current flows through the metal filament of a light bulb, electrical energy is converted into different forms of energy. In the case of a light bulb, the conversion involves the production of light and heat energy. Explanation: 1. When the current passes through the metal filament, it encounters resistance. This resistance causes the filament to heat up, which in turn produces heat energy. This is why light bulbs become hot when they are turned on. 2. As the filament heats up, it begins to glow and emit light. This glowing and light emission are a result of the conversion of electrical energy into light energy. Therefore, the light bulb produces both heat and light energy as a result of the electric current flowing through its filament. Answer: b. Heat and light energy So, when electric current flows through the metal filament of a light bulb, it generates both heat and light energy, making the bulb illuminate and giving off warmth as well.
