A resistance R carries a current i. The power lost to the surrounding is `lambda (theta - theta_(0))`. Here, `lambda` is a constant, `theta` is temperature of the resistance and `theta_(0)` is the temperature of the atmosphere. If the corfficient of linear expansion is `alpha`. The strain in the resistance is
A. `(alpha)/(lamda) l^(2)R`
B. `alphalambda//R`
C. `(alphal^(2)R)/(2lambda)`
D. proporitonal to the length of the resistance wire
