minus-squareFuglyDuck@lemmy.worldlinkfedilinkEnglisharrow-up9·1 year agoSurge protectors don’t use capacitors. They use a variable resistance circuit- usually metal oxide varistors. When the supply is at the correct voltage, it just goes through them. When it’s too high (a surge,) the resistance increases and excess voltage is sent out a fork to ground
