Normal Operation: Under normal conditions, the current flowing through the circuit breaker does not generate excessive heat, and the bimetallic strip remains straight. Overload Condition: When the current exceeds the breaker''s rated capacity, the excess current generates heat, causing the bimetallic strip to bend.
A capacitor stores energy in an electric field between its plates, while a battery stores energy in the form of chemical energy. Q: Why use a capacitor over a battery? A: Capacitors are used over batteries in certain applications because they can charge and discharge energy rapidly, have a longer lifespan, and are less affected by temperature changes.
