OverviewHazards and safetyHistoryTheory of operationNon-ideal behaviorCapacitor typesCapacitor markingsApplications
The hazards posed by a capacitor are usually determined, foremost, by the amount of energy stored, which is the cause of things like electrical burns or heart fibrillation. Factors such as voltage and chassis material are of secondary consideration, which are more related to how easily a shock can be initiated rather than how much damage can occur. Under certain conditions, including …
