When a home circuit breaker opens the lights in some rooms go off but the lights in some rooms stay on. Explain why.?

The circuit breakers in a panelboard feed separate circuits. The lights that stay on are on a different circuit than the ones that go off. To fine the circuit that feeds the lights that stay on, go to the panelboard and turn off the breakers one by one until the lights go out. This is the circuit that feeds that circuit of lights. Remember that lights and receptacles can be on the same circuit together.

What is a switch that opens a cuircut when too much current is flowing?
Where I'm from, it's called a "circuit breaker".A circuit breaker.
The part of a circuit that closes or opens a circuit?
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
Working principle of air circuit breaker?
circuit breaker is a switch that turned off when there is a short circuitAnswerAn air circuit breaker is a high-voltage circuit breaker whose tripping and closing mechanisms are (usually) operated pneumatically, and whose arc is extinguished by a blast of air -hence the alternative name 'air-blast circuit breaker'.
How a circuit breaker prevent from too much current flowing into device?
The current (in question) flows through both the circuit AND the circuit breaker [they are in series]. Within the circuit breaker when the current exceeds the preset limit it will open the circuit thus stopping all current flow. There are two common ways of doing this 1) magnetism - a coil pulls a switch open 2) thermal - a bimetallic strip bends away from its contacts, which opens the circuit.
A circuit protection device that opens when overloaded and then automatically resets is known as a?
If it is on a motor, it is called a self or auto resetting IEC thermal overload protection device. If it is on anything else, it is a bad idea.
What is a switch that automatically opens if a current is too high?

What part in an electric circuit opens and closes the circuit?
A switch, switching transistor, or circuit breaker usually does.
What circuit protection device can be reset after it opens?
A circuit breaker is an overcurrent device that can be reset after it has opened.
What is a switch that automatically opens if the current is to high?
That would be a circuit breaker.
What happens to a switch that automatically opens the current if it is too high?
Circuit Breaker.

What is a difference between 10KA and 22KA circuit breakers?
The previous answer is incorrect, and I would advise that user to not give out information if they are going to give completely misguided information. The interrupting rating of a breaker is the maximum current that the breaker is designed to handle, at the breaker's rated voltage, before damage will occur to the breaker. A breaker will trip at FAR LESS than the interrupting rating, but it is extremely dangerous to expose the breaker to any situation where it will have more than the rated interruption current. the breaker is designed for. The reason some breakers are rated at 22kA instead of 10kA is because they typically have far larger conductors hooked up to them, so with the lowered impedance on the circuit there is more of a chance for the breaker to experience a higher fault current at the breaker. So electricians install 22kA breakers to handle the higher "available fault current."

What happens when a circuit breaker opens?
to much lightningiam is released into the air therefor starting a zombie Apocalypse
What is air circuit?
You may be referring to an air circuit breaker or, more accurately, and air-blast circuit breaker. This is a type of high-voltage circuit breaker in which the electrical arc, drawn when it opens, is stretched and snapped by a blast of air directed between the separating contacts -so the air is used as a method of extinguishing the arc. Often, these breaker's mechanisms are also driven by compressed air.
