=> Ohm's law. The Temperature should remain constant
(b) Name the electrical property of a material whose symbol is "omega".
=> Resistance
(c) Name a material which is used for making the heating elements of electrical appliances.
=> Nichrome wire
(d) Give two reasons why the above material is used for the said purpose.
=> Two reasons for the same are :-
Firstly nichrome is an alloy, it has a higher resistivity and consequently a higher resistance.Therefore, it will resist the flow of charges more and lead to development of heat faster.
Secondly alloys like nichrome don't oxidise,i.e burn easily at high temperatures.
hope it helped you friend !!
