Capacitors are rated by which two categories?

Capacitors are rated by voltage and capacitance, specifically measured in microfarads (uF or µF). The voltage rating indicates the maximum voltage the capacitor can safely handle without the risk of breakdown, while microfarads quantify the capacitance, which measures the capacitor's ability to store electric charge.

The voltage rating is crucial because exceeding it can lead to capacitor failure, potentially damaging equipment or causing safety hazards. Capacitance, measured in microfarads, reflects how much charge the capacitor can hold. This information is essential for technicians to choose the right capacitor for a specific application.

While other options mention terms related to electrical concepts, they do not correctly define the essential ratings for capacitors.
