why the earth terminal in three pin top is longer than rest
of the two terminal and of bigger size?
Answer Posted / sunil ulange hit nidasohi
Because Current always take low resistance path, i.e
Resistance is inversely propotional to Area,
means higher the fault current, lower the resistance,
Higher the conducting area i.e Earth terminal area is higher
than normal pins
R = ql/A, Resistance increases, area decreases

how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???
