What else can I help you with?
If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
Is the amount of current that flows in the wire of electric circuit the same as the current that flows in the filament of the light connected in that circuit?
yes
What would happen if a wire in a parallel circuit broke?
All of the current would travel down the remaining intact wire - possibly overheating.
What happens when you disconnect the wire from the battery?
Disconnecting a wire from a battery would break the circuit. If the battery was powering a bulb, the lamp would go out.
When using a 3 wire control circuit to control a magnetic motor starter the part that will open the control circuit when an overload occurs will be?
The part that opens the circuit is the overload blocks that are situated below the magnetic starter and before the motor load. The latest addition to the electrical code book states that the "hot" wire goes through the overload contacts first before feeding the 3 wire control system. With the supply voltage in this position the whole circuit becomes de-energized when the motor load trips the circuit. The old standard practice on a 3 wire control system, the neutral was connected to the overload relay contacts. When the overload relay tripped it opened the neutral of the coil circuit and the starter dropped out
What is the use of wire gauge?
Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
Which wire is the common wire in a typical electrical circuit?
The common wire in a typical electrical circuit is the neutral wire.
How do you change wire fuse for circuit breaker?
A circuit breaker does not have a wire fuse in it.
Where does the wire come from in an electrical circuit?
The wire comes from the installer or manufacturer of the circuit.
Can one use 1 circuit of a 3 wire plus ground 2 circuit cable as a GFI circuit with the other as a lighting circuit?
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
Is the black wire in this electrical circuit designated as the hot wire or the neutral wire?
In an electrical circuit, the black wire is typically designated as the hot wire.
Is the white wire in this electrical circuit designated as the hot wire or the neutral wire?
In an electrical circuit, the white wire is typically designated as the neutral wire.
Is the black wire hot or neutral in the electrical circuit?
In an electrical circuit, the black wire is typically the hot wire.
Is the black or white wire hot in this electrical circuit?
In an electrical circuit, the black wire is typically the hot wire.
Is the hot wire correctly connected to the ground wire in the electrical circuit?
No, the hot wire should not be connected to the ground wire in an electrical circuit.
Is the white wire hot or neutral in the electrical circuit?
In an electrical circuit, the white wire is typically used as the neutral wire, not the hot wire.
Which wire is the hot wire in an electrical circuit?
The hot wire in an electrical circuit is the wire that carries the current from the power source to the device or appliance.
