Question

answer this fastly
a)in the above materials which has more intensity
b)the restivity of filament used in the bulb
c)which material has more conductivity
d)which material is used as heating element ​

Answer 1

Explanation:

I will help you this friend,

a) I think you meant intensity for resistance,

So, Drinking water.

b) The filament used in bulb is made of tungsten,

It's resistivity is 5.20×10^-8 ohm metre.

c)The material with least resistivity is highest conducting. So, Sliver wires are used for conducting (but copper wires also because they are cheap than silver).

d) the material like metals but more generally alloys are used for heating because of higher resistivity. So, Nichrome (and tungsten also).

I hope it helps,

Please mark as the brainliest answer.
