| 1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
| 2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
| Q1 ⇒ The material used for the manufacture
of grounding wires is galvanised steel [other wrong options] [Discuss in forum] |
| Q2 ⇒ In medium transmission lines the shunt
capacitance is taken into account in all of the above [other wrong options] [Discuss in forum] |
