A) \[50{}^\circ C\]
B) \[60{}^\circ C\]
C) \[70{}^\circ C\]
D) \[80{}^\circ C\]
Correct Answer: D
Solution :
Use\[{{R}_{t}}={{R}_{0}}(1+\alpha t)\] Here\[20={{R}_{0}}(1+20\alpha )\] \[60={{R}_{0}}(1+500\alpha )\] Here\[{{R}_{t}}=25\,\Omega \] Solving we find\[t=80{}^\circ C\].You need to login to perform this action.
