Current is the flow of electric charge in a circuit.
Current is measured in Amperes (A)
It is the rate of flow of electric charge through a conductor
Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically
A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
Circuit breakers detect faults in the electrical system and interrupt the flow of electricity to prevent damage.
They consist of a switch mechanism and a tripping mechanism that activates when a fault is detected.
Circuit breakers can be reset manually or automatically after tripping.
