Answer 1

Answer:

If R, is the resistance of a coil of copper at

1'C and Ry is the resistance at TC and also

the resistance temperature coefficient of

copper per degree centrigrade at 0°C is

1.

R

then is given by

234.45 RI

1 + 1

1 + 234.45

(A)

(B)

1+T

1 + 234.45 T

234.45 + 1

(C)

234.45 + ?

234.45 + T

(D)

234.45 + T2
