1.	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
Answer» `(alpha)/(lamda) l^(2)R` `alphalambda//R` `(alphal^(2)R)/(2lambda)` proporitonal to the length of the RESISTANCE wire Answer :A
