D.c network and theorems

              D.c NETWORKS AND THEOREMS     ____________________________________________ INTRODUCTION _     °in the study of electrical engineering which involves the study of the behaviour of electrical systems and devices the knowledge of electric circuit theory is very essential. We are there for beginning  our study of electrical circuit theory with the study of various  methods off the network analysis and principle theorems which have been developed for solving problems and complex electrical networks °even through the discussion in the chapter is restricted to D.C circuit only, it is equally applicable to A.C network in the case of A.C networks, the only difference is that the impedance's are used instead of just ohmic resistance's. Since the impedance as well as as currents and voltages in such(ऐसा) circuits are expressed (व्यक्त करना) by complex numbers the algebraic manipulation are more extensive(बहुत बड़ा)...

              SURVEYING AND LABELLING 1.0  SURVEYING:- Surveying is a branch of civil engineering. Surveying is used to represent the general features of land in their proper relative positions. rom the measurements obtained by surveying, drawings are prepared, which may be in the form of a plan or a map. Surveying is defined as, "the process of toking measurements on the earth surface to determine the relative positions of different points upon it so that, the points may be represented on a plan or a mop Surveying deals with the measurements in horizontal plane 1.1 Purpose of surveying:- 1 To determine the relative positions of existing features of the ground. 2. To layout out mark position or proposed structure on ground. 3. To determine areas, volumes and other related quantities. 4. To prepare map of country and detailed locations of cities, towns, villages and major roads. 5. To prepare engineering plan in detail and section of va...
