English: So, therefore, I can write I which is a current is going to be αPN (TH -TC)/(1+𝑚) RP +RN therefore, the external work WL is going to be I² RL and you can show it to be as α²PN (TH -TC)²/(1+m² RP +RN)² RL is what m(RP +RN).
Telugu: R_(N) కాబట్టి, బాహ్య పని W_(L)=I² RL అవుతుంది మరియు మీరు దానిని α²PN (TH -TC)²/(1+m² RP +RN)² RL అంటే m(RP +RN).
