Question: you are asked to predict the minimum melting time of...

Question details

You are asked to predict the minimum melting time of a copper fuse in free air with an initial temperature of 75C given an experimental point for an initial temperature of 25°C. The given point is: l-1550 A, t 0.107 sec, with an initial temperature of 25°C. What would be the minimum melting time for the same current if the initial temperature were 75°C (Assume that the model i2t Km is valid.)
