PFC, or protective fault current, refers to the electrical current that flows during a fault condition, such as a short circuit or ground fault in an electrical system. This current is essential for protective devices, like circuit breakers and fuses, to detect and isolate the fault, thereby preventing damage to equipment and reducing the risk of fire or electrical hazards. The magnitude and duration of PFC can influence the design and rating of protective devices to ensure system safety and reliability.

What is the direction of current due to flow of electrons if it is not conventional current?
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
How does a static discharge differ from an electric current?
It doesn't differ at all, an electric current is electricity that is moving in a current and when static electricity is discharged from an object it creates a current from one object to another
What is the rate at which electrons do work?
Current. The flow of electrons is the flow of a moving charge. The rate of flow is current (the amount of charge that flows in a set time). The equation is: I = Qt Hope this helps.
Why must a circuit be closed in order for current to a flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
Electron current flow theory considers electricity to be the flow of charge carries which are what in polarity?
When we consider electron flow, we think of moving electrons. The electron has a negative charge. This model of current flow, the electron current flow model, follows the movement of those negative charges.As a contrast, we might consider what is called conventional current flow. And that the model of current involves the movement of charges with a positive polarity.
What is sentence for current?
The river's current is strong in March. I couldn't get the current to flow so we still have no lights. Something that happened last year is not really a current event.
What are the advantages of co-current flow?
A Counter-current flow has more advantages as comapared to a co-current flow.
What is a current flow restrictor?
A current flow restrictor is a diode.
How do you draw a flow?
There are different boxes used in a flow chart. A flow chart is basically a "If - then" chart. If this event happens then go to next event, if not go to alternate event.
Voltage is pressure and current is flow what opposes flow?
Reverse current.
Is it possible to flow current wireless?
No it is not possible to flow current wireless.
How do you draw a flow diagram?
There are different boxes used in a flow chart. A flow chart is basically a "If - then" chart. If this event happens then go to next event, if not go to alternate event.
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
What is a current world event?
A current world event is...never mind about that...
What is the direction of current due to flow of electrons if it is not conventional current?
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
What is the flow of current through a wire known as?
The flow of current through a wire is known as electrical current.
How are convention current caused?
Conventional current flow is current flowing from positive to negative as opposed to electron flow where current flow is from negative to positive. See Related Links
