[1] 1.5 What is the importance of studying Electron Theory? [2] 1.6 State the factors of Torque. [3] 1.7 An electric soldering iron is heated from a 220-V source and takes a current of 1.84 A. The mass of the copper bit is 224 g at 16°C. 55% of the heat that is generated is lost in radiation and heating the other metal parts of the iron. Would you say this is a good or a bad electrical system and motivate your answer?
