Is it true or false that a circuit breaker must be replaced after a short circuit occurs?
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.
What else can I help you with?
True or false A device that is used to open the circuit when the current flow is to great is a disconnect switch?
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.
True or false in a series circuit circuit current is the same throughout the circuit?
A series circuit only has one loop
True or false switches can control each branch in a parallels circuit separately?
true
What is the result of True AND False OR 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
When applying loads to the primary distribution center you can close all of the circuit breakers on the connected secondary distribution center at once?
false
True or false A device that is used to open the circuit when the current flow is to great is a disconnect switch?
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.
In an electric circuit the ground prevents current from flowing in the circuit.?
false
True or false the national bank replaced the federal reserve system?
It is false that the National Bank replaced the Federal Reserve System.
True or false a closed circuit is an incomplete loop?
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.
True or false in a series circuit circuit current is the same throughout the circuit?
A series circuit only has one loop
Current is additive in a series circuit?
False
A circuit diagram shows the componens of a circuit and how they ae arranged. True or False.?
True!
Meiosis occurs when gametes are needed during sexual reproduction. true or false?
False
Are The lungs are the primary organs in the Systemic circuit?
No ; False
In an electric circuit the ground prevents current?
false
is the layer of the atmosphere where weather occurs is the thermosphere true or false?
False. The majority of weather occurs in the troposphere.
In an electric circuit the ground prevents current from flowing in the circuit true or false?
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.
