WebThe heat dissipation within a resistor is simply the power dissipated across that resistor since power represents energy per time put into a system. So the relevant equation is the equation for power in a circuit: P = IV = I^2 R = \frac {V^2} {R}, P = I V = I 2R = RV 2, Microscopically, Ohm's law is a statement about how application of an electric fiel… WebJul 30, 2016 · A novel tuning actuator in QCLs was recently developed by Alpes Lasers. It consists of a small heating element incorporated next to the active region of DFB QCLs [].This integrated heater (IH) is a resistive element driven by an electrical current, which heats the laser via Joule’s dissipation.
Webwe can conclude that 1W of power would rise the resistor's temperature by 155-70=85C and that the thermal resistance between the resistor and ambient is 85C/W. This can be used to estimate the temperature rise of the resistor while dissipating a specific power. So far so good until we compare the above calculations with the temperature rise ...
