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 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.
What is unsymmetrical current?
it means those currents those are short circuit.
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.
How many potentially different currents are there in the circuit shown?
In the circuit shown, there are potentially three different currents.
What is the sum of currents is known as?
The sum of currents in a circuit is known as total current, which is the combined flow of all individual currents passing through the circuit components. This total current is conserved in a series circuit where it remains constant throughout the circuit.
When electric currents are not allowed to flow the circuit is called a?
When electric currents are not allowed to flow, the circuit is called an open circuit. This means that there is a break in the circuit, preventing the flow of electricity from one point to another.
What happens if current flows through 2 parallel current in the same direction?
With the possible exception of some circuits that have inductance and capacitance in parallel and are excited by a pulse or an alternating voltage, the currents in two parallel branches of a circuit are ALWAYS in the same direction.
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.

What is unsymmetrical current?
it means those currents those are short circuit.
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
