Wp/pgh/Lectrics
Lectrics is 'e study an use o lectric compoenents an circuits 'at controls 'e floe o lectrons er other lectric charged particles.
'E moest basic compoenents used in lectrics are resistors, capacitors, an tight er loose wound bits o wahr cawed inductors. Older lectronics used glass er metal vacuum tubes da control 'e floe o lectrons. By 'e late 1960s an early 1970s,'e transistor started da take 'e place o vacuum tubes as control compoenents. Abaht 'e same time, integrated circuits came inda normal use. Integrated circuits made it pawssible da loewer 'e number o compoenents needed da make lectric products.
