Since my job is related to led drivers and ballasts i get confused with some questions.i see that the capacitor that is placed after diode bridges decreases the power factor and when we remove it we can achieve a higher pf.so i think that our power factor is a leading pf. So why we know most of the loads as inductance loads?and why do we just have capacitor banks?not inductors bank?how companys compensate leading power factor?

How do you compensate leading power factor?

Also, why we know most of the loads as inductance loads?  and why do we just have capacitor banks, not inductors bank?
