1 Note these General and essential Points - - - It is essential to give question number and sub question number in the margin provided.Next question ( NOT SUBQUESTION) must start on next page.Draw relevant diagrams even if not asked.All figures must be drawn by pencil. They must be labeled and sufficiently large.SAFE HANDS
2 Note these Points - - -While solving numerical problems first write given data convert it into S.I. units. Write the formula needed and substitute the values. Do calculations using log or direct in a box call it as rough work ( it should be neat and good looking)The answer of numerical problem must be with units and should be in a box.While deriving any expression remember that your next step is outcome of previous step.If you want to cancel some part don’t cancel it as“Parallel axis theorem : If Iz is MI about an axis perpendicularit should be as—
3 Points you need to remember Diagrams must be labeled and arrow must be shown for current and vectors. The key must be introduced and polarities of A, V, source, must be shown.Show polarity of cellsArrow on wire indicating direction of currentRemember to show variable resistance (rheostat), key, Galvanometer, source of e.m.f. with polarity ( take proper care when used in potentiometer)All most every definition must be with example.If question is about comparison or assumptions then just give the list of points.
4 Points to rememberWhile doing numerical problems of meter bridge or Whetstone's network better have figure.When ac is applied direction of current is not to be showedRemember to indicate transformer, primary, secondary, load resistance, “e” input ac voltage, Vo output voltage, if full wave rectifier then center tap, direction of current in load resistance connected to output.Once you note down data in SI units think about formula needed and use it .
