Answer Posted / rupinder singh
2nd and 5th harmonics means- voltages or current having frequency two times and five times the fundamental power frequency..eg. if fundamental power freq. is 50Hz then 2nd Harmonics is a current or voltage having frequency 100Hz and that fifth Harmonic having frequency 250Hz.

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???
