What is a Circuit Breaker?

Circuit breakers are an electrical switch that protects an electrical circuit breaker against damage from short circuits, overcurrent/overload, or short circuit. {It interrupts current flow following|The circuit breaker interrupts current flow upon|They interrupt current flow after} {detection of faults by|the detection of faults by|the detection of faults using} protective relays.

How Circuit Breakers work?

Circuit breakers are {an essential|a vital} {safety device in today’s world|security device in the modern world|safety tool in today’s society}. {When there is too much|If there is excessive|If there’s too much} {electricity flowing through a building’s|electrical current flowing through the building’s|electricity flowing through a structure’s} {electrical wiring, these|electric wirings, the|wires for electrical power,} {machines|devices} {turn off the power|shut off power|stop the flow of electricity} until the {problem can be|issue is|issue can be} {fixed|repaired|solved}. {Household electricity|Electricity for household use|Electrical power for homes} without circuit breakers{ or the| or|, or the} alternative of fuses {would not|wouldn’t|will not} be {possible|feasible} {due to the risk|because of the danger|because of the possibility} of {fires, equipment malfunctions,|fires, malfunctions of equipment,|explosions, equipment malfunctions} and other {problems|issues}.

Understanding how {your household electricity|the electricity in your home|electricity at home} {works is essential to understanding|functions is crucial to understand|operates is vital to comprehend} circuit breakers.

Three {main attributes are what|primary attributes|major attributes are what} {define|defines|are used to define} electricity:

• Voltage
• Current
• Resistance

{Voltage refers to|The term “voltage” refers to|Voltage refers} the “pressure” {which makes|that causes|that makes} {an electric charge|the electric charge|the charge electric} move. Current {measures the|is the measure of|is a measure of the} charge’s “flow”{, the rate| and the speed| which is the rate} {at which it moves|that it flows|at which it travels} {through|across|within} the conductor. {The conductor provides|Conductors provide|The conductor is able to provide} some resistance to {this|the} flow. {This resistance varies depending upon|The resistance is based on|This resistance differs based on} the {conductor’s size and|size of the conductor and its|conductor’s dimensions and the} composition.

{All three are interrelated|The three are all interconnected|All three are interconnected}. {You can’t alter one|It is impossible to alter one|One cannot be altered} without {changing the other|altering the other|altering the others}. {The voltage divided|A voltage that is divided|This is the voltage multiplied} by{ the|} resistance is {called|known as|referred to as the} current. {It’s commonly known|It is commonly referred to|It’s often referred to} {as|by the formula|in the form} I = (v/r). This {makes sense intuitively|is logical|makes sense}{: Increase| increase| increasing} the pressure {that works|acting} {on the electric|upon the|with the electrical} charge{,|} or {decrease|reduce} the resistance {to allow more|in order to allow more|to allow for more} {charge to flow|charged to move|charges to be able to circulate}. {The flow of charge|Charge flow} {will be reduced if|is reduced when|will decrease if} {you increase resistance|the resistance is increased|there is an increase in resistance,} or {decrease|reduce|lower} pressure.

The Working Principle of the Circuit Breaker
