The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
yes
Disconnecting a wire from a battery would break the circuit. If the battery was powering a bulb, the lamp would go out.
All of the current would travel down the remaining intact wire - possibly overheating.
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
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.
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
The wire comes from the installer or manufacturer of the circuit.
A circuit breaker does not have a wire fuse in it.
Yes, you install a GFCI on a 2 wire circuit.
A multi-wire circuit requires only one equipment grounding conductor for the entire circuit. Each branch circuit within the multi-wire setup shares this one ground wire as it connects to the main grounding point.
The wire that connects the power source to the rest of the circuit should contain the fuse. This is typically the wire that leads directly from the positive terminal of the battery or power source. Placing the fuse in this wire helps protect the circuit in case of a short circuit or overload.
The smaller the wire size used in a circuit limits the amount of current that is allow to be flow through that circuit.
A parallel circuit is :)
No, a wire wrapped around a magnet is an example of a closed circuit, as the wire forms a continuous loop for the flow of electric current. An open circuit is a circuit that is interrupted, preventing the flow of current.
A circuit with a broken wire is an open circuit, meaning there is a gap in the pathway for electricity to flow. This interruption stops the current from completing its loop, resulting in a non-functional circuit. Fixing the broken wire will restore the connection and allow the circuit to operate properly.
Close circuit is a complete circuit of battery wire bulb and a switch
