a water geyser uses heating element which is highly resistant to the flow of electricity.Why?Can we use the same material in connecting wires? Explain.
friends,
answer with correct answer please.

Answer:
A water geyser uses heating element which has a high resistance because resistance provides heat and heats up the water and the main motive of geyser is to provide heat. We can't use it in connecting wires because if we use it in connecting wire, a lot of current would be wasted/lost in form of heat beacuse (resistance always provide heat), and we don't need to waste current rather want to transport it by wires

Answer:
Answer
Nichrome is used for making heating element of electrical appliances. Because nichrome does not oxidize and burn easily at high temperature i.e.it has higher melting and boiling point than metals. Thus it does not melt even when a large amount of heat is produced due to passage of current. Moreover, It has higher resisistivity and consequently a higher resistance.Therefore, it will resist the flow of charges more, and lead to development of heat faster
