Fundamentals | Capacitor Guide
What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field.This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.

Does capacitance of ceramic capacitors change by temperature?
What are capacitance temperature characteristics in capacitors? Capacitance of ceramic capacitors changes by ambient temperature. This change is called capacitance temperature characteristics. This is caused by the material used in ceramic capacitors, and generally occurs on ceramic capacitors of other companies.

High voltage circuit breaker standards—comparative guide
The standards set different temperature limits for current carrying parts, connection points, and contacts. The allowed temperature rise for the insulating parts vary based on the insulating class used and the ambient temperature of the air surrounding the equipment. Temperature is a function of the resistance of the conductor and the
