網頁2024年6月20日 · Initially, the bulb was not glowing because the voltage required to make the bulb glow was not sufficient. With the addition of another cell, the voltage increases, i.e. the current through the bulb increases more than a particular value and the bulb starts glowing because it gets sufficient energy to heat its filament. Question 13 網頁2016年2月8日 · 7. If the bulb is lit when you pour water on it, it will undergo thermal shock. Some parts cool down and shrink, while other parts are hot. This causes very large …
網頁(iii) The conductivity of the liquid may be very low and so the current flowing through the circuit may be too weak to produce enough heat in the filament of the bulb so as to make it glow. (ii) The battery may be exhausted and does not have sufficient energy to generate electricity. (iii) The bulb may be fuse. (iv) Connections may be loose.
