408. Problem 33.26 (RHK) In the circuit shown in the figure , , and have constant values but R can be varied. We have to find an expression for R that results in the maximum heating in that resistor. |
Solution: Click For PDF Version We will find the current flowing through R. We have a multi-loop circuit with one junction. Equations that follow from Kirchoff’s laws are Also, Rate of Joule heating in the resistance R is
We find the extremum solution of by requiring This condition gives the equation As we have |
