SUMMARY

The equation for calculating R-value in insulation is essential for determining thermal resistance in building materials. R-value is defined as the measure of resistance to heat flow through a given thickness of material, typically expressed in square feet and degrees Fahrenheit. For accurate calculations, it is crucial to refer to reliable engineering resources or insulation manufacturers' specifications. This discussion highlights the need for clarity in distinguishing between electrical concepts like Ohm's Law and thermal insulation calculations.

PREREQUISITES
  • Understanding of thermal resistance concepts
  • Familiarity with insulation materials and their properties
  • Basic knowledge of building construction principles

can some one give me the r-value equation and possible a site that has the information as well, thanks

More info please.

Do you mean Ohms law or the equation you use to figure out how much
thermal insulation to put on the walls of your house?

You're in the wrong forum. Try general engineering.
 

Thread 'uA709 op amp compensation'

Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
