Hello Mapes, I am a bit confused now because i get some strange numbers by the above equation. I do not know Heat Capacity in J/K of titanium (material of resistor). Therefore, I used \Delta T=(I^{2}Rt)/(mC) and take the mass of resitor into account. The resistor is made of titanium and is...
Hello Mapes, the last thing that i want to know is: In case if i want to take the conductive heat transfer into account, then is it correct to replace Q=mc\Delta T with Q=[mc\Delta T]+[kA/\Delta x],
where k is the thermal conductivity of the material. I am not sure if Q will be sum of two...
Mapes, Thanks for the reply. The total energy dissipated in the resistor is given by: E=I^{2}Rt. So , If i assume that there is no heat transferred then the joule heat will increase the temperature of resistor. The Heat energy is given by Q=mc\Delta T. And by comparing the two equations I will...
I want to find the increase in the temperature of a resistor due to joule heating. I mean that if we apply some electrical power to a resistor then the electrical energy is converted to heat energy due to joule heating. The heat energy will increase the temperature of the resistor. Is it...
