Bad AC Capacitor Symptoms – Here''s What to Look For
An AC unit that shuts down randomly could mean the AC capacitor is going bad. When your AC shuts down randomly, the capacitor is having trouble keeping the AC unit running. You''ll hear the AC turn on, but then shut off abruptly later—even when your thermostat is still calling for cooling.

Capacitors | Brilliant Math & Science Wiki
2 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity …
