Question

Meera doesn't have a night lamp in her room. She covered the bulb of the room with a towel to get a dim light. Has she taken the right step? Justify the answer in simple words

Answer 1

* If it is an incandescent lamp, the increase in temperature of the towel could set it on fire,

* If the towel is wet, there could be a short circuit

Step-by-step explanation:

Covering the lamp with a towel has several problems:

* If it is an incandescent lamp, the increase in temperature of the towel could set it on fire, which could be a danger

* If the lamp is not incandescent, the temperature rise of the towel is not very high,

* If the towel is wet, there could be a short circuit due to the humidity of the lamp with the wet towel

* If the towel is wet when touched, there could be a shock towards the person due to the electrical conduction

Consequently, covering the bulb with a towel is a serious mistake.
