For the first part, given temperature resistance relationship, rt equals a, r0, exponential, b by t, where a and b are constant.
00:14
At 0 degree temperature, resistance will be given 3980 is the resistance at 0 degrees celsius, equal a r0, e, b by 273.
00:33
Converting 0 degree into kelvin, it is to 773 kelvin.
00:37
So this is first equation.
00:40
And at 40 degrees celsius, at 50 degrees celsius, 794 is the om, a, r0, e, b, y, 323.
00:53
Converting 50 degrees celsius into kelvin, it is 323 kelvin.
00:59
So it is 323 kelvin.
01:02
So dividing equation first by second.
01:04
So it is 3980 divided by 794.
01:12
So it is a r0 e by 273 divided by a .r .0 b by 323.
01:28
A r0 got cancelled...
