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.

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.
Do Parallel circuits have only one path for current true or false?
No. By definition, a parallel circuit occurs when there is more than one alternative path.
True or false in a series circuit circuit current is the same throughout the circuit?
true
In an electric circuit does the ground prevent currents from flowing in the circuit?
false
In a series circuit the current is shared between the loops true or false?
A series circuit only has one loop

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.
Is heat the fusion that occurs in a substance?
Yes, it is the fusion that occurs in a substance. False
In an electric circuit the ground prevents current from flowing in the circuit true or false?
False
Do Parallel circuits have only one path for current true or false?
No. By definition, a parallel circuit occurs when there is more than one alternative path.
True or false a closed circuit is an incomplete loop?
False.
True or false in a series circuit circuit current is the same throughout the circuit?
true
is the layer of the atmosphere where weather occurs is the thermosphere true or false?
False. The majority of weather occurs in the troposphere.
