How does a circuit breaker know that the voltage is high or low and trip off?
A circuit breaker doesn't respond to excessive voltages, but to excessive currents (overcurrents). A miniature circuit breaker, the type you have at home, has a bimetallic strip and a coil, either of which will initiate a trip in response to excessive temperature (overload currents) or excessive magnetic flux density (short-circuit currents).
What is unsymmetrical current?
it means those currents those are short circuit.
What happens in a circuit to voltage when current flows?
A: There is a relationship one needs the other both can coexists but not each alone.
Why use an enclosed circuit breaker?
To protect the wiring from overheating and catching on fire.AnswerThe term, 'switchgear', describes a variety of switching devices including circuit breakers and isolators (disconnects).A circuit breaker is an overcurrent protection device. Overcurrents are overload currents (due to too much load for a given circuit) or short-circuit currents (due to electrical faults).
Kirchoff's law that states the sum of the currents entering the node is equal to the sum of the currents leaving the node on a parallel circuit?
KCL (Kirchoff's Current Law) applies to any circuit, not just parallel circuits. The sum of the currents entering a node will always equal the sum of the currents leaving the node. KVL states that the sum of the voltages around a closed loop is always zero.
Can electric currents run through a open circuit?
No

How are parallel circuit and series circuit the same?
They are not. They are connected differently, and the voltages and currents behave in different ways.
When electric currents are not allowed to flow the circuit is called a?
non conductor

The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
What does circuit mean in science?
circuit means a closed path followed or capable of being followed by an electric currents

How is a total current in a parallel circuit worked out?
sum the individual branch currents
What protects circuits from dangerously large currents?
resistors circuit breakers fuses
What is the role of insulators such as plastic rubber and cloth covering wires and other conductors in a circuit?
Insulators are used to keep electrical currents in the circuit. If they do not follow the entire circuit, it would be a "short circuit".
