Question

A nichrome element has a resistance of $75.3\Omega$ at ${27}^{\circ }C$. When 230 V p.d is applied and a study state temperature is reached, the current flowing through it is 2.68 A. If $\propto =1.7\times {10}^{-4\circ }{C}^{-1}$, find the steady state temperature

• A. ${1000}^{\circ }C$
• B. ${700}^{\circ }C$
• C. ${950}^{\circ }C$
• D. ${848}^{\circ }C$

Answer 1

The correct option is D ${848}^{\circ }C$
