A circuit breaker must be reset to ON after a short circuit but does not need to be replaced. It depends on the type of CB. A fuse is also a circuit breaker and it needs to be replaced after a short circuit. Relayed circuit breakers have to be "picked up" after a dropout and need not be replaced as such.
False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.A disconnect switch is a manual device that isolates or turns off the load.
A series circuit only has one loop
true
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True

False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.A disconnect switch is a manual device that isolates or turns off the load.
false
It is false that the National Bank replaced the Federal Reserve System.
False. A closed circuit is a complete loop where electricity can flow continuously from the power source, through the components, and back to the source.
A series circuit only has one loop
False
True!
False
No ; False
false
False. The majority of weather occurs in the troposphere.
In an electric circuit, the ground does not prevent current from flowing. Instead, it provides a safe path for electrical current to return to the earth in the event of a fault. It's a protective measure to prevent electrical shock hazards by maintaining the voltage stability in the circuit. The normal operation of the circuit isn't affected by the grounding system.
