Question

If the current through a circuit is too weak, we can use LED because it glows even when a weak electric current flows through it.

• A. True
• B. False
• C. Ambiguous
• D. Data insufficient

Answer 1

The correct option is A True

Answer is A.
The electric bulb has a filament called tungsten when electricity passes through this filament, it heats up and glows. This heat is generated due to the passage of electric current and the drift of electrons due to the current and the resistance it causes.
When the current flowing through the circuit is not sufficient to produce the heating effect for the electric bulb to glow, a LED bulb can be used instead as the LED bulb requires only very less amount of current to glow.
Hence, the statement is true.
