A power transistor dissipates 0.2 W of power steadily in a specific environment. The amount of heat dissipated in 24 H, the surface heat flux and the surface temperature of the resistor are to be determined. h= 18 Wm² C
In this problem, the amount heat dissipated ,surface heat flux and surface temperature have been calculated by the help of Fourier's law of conduction. The solution is complete and well presented.
