How do you calculate the current required to melt 14 gauge wire insulation?
To calculate the current required to melt 14 gauge wire insulation, you need to know the specific heat capacity and melting point of the insulation material. You then use the formula Q = mcΔT to calculate the heat energy required to melt the insulation, where Q is the heat energy, m is the mass of the insulation, c is the specific heat capacity, and ΔT is the temperature increase needed to reach the melting point. The current can be estimated using the formula I = Q / t, where I is the current, Q is the heat energy calculated earlier, and t is the time over which the heat is applied.
What factor most influence the amount of energy needed to change the temperature of a substance?
