Effects Heating Resistor

Click For Summary

SUMMARY

The heating effect described by the formula E=I²Rt quantifies the energy dissipated as heat in a resistor due to the flow of electric current. This relationship is derived from the power equation P=IV, where substituting V with IR leads to P=I²R. The discussion emphasizes the direct correlation between current (I), resistance (R), and the resultant heat energy (E) generated over time (t). Understanding this principle is crucial for applications involving resistive heating in electrical circuits.

Power, P=IV where V=IR. Hence P=I^2R.

This explanation of http://en.wikipedia.org/wiki/Resistor#Power_dissipation" should answer your question.

Thread 'Truss analysis problem'

TL;DR: determine the internal force of member OA Hi I'm struggling with this problem. I have calculated the angle to be 45 degrees with tan(theta) = a/a. A is a roller which only has Ay and O has Ox & Oy as a fixed pin. (see fbd.png) is my FBD correct?
