spt-1, spt-2 & spt-3 wire difference: #3 has the thickest exterior ..................................
The longer answer: spt-1, spt-2 & spt-3 = Stranded, Parallel, Thermoplastic (lamp cord) = "zip wire." It is the commonly-seen, flat, 2-conductor electrical cord found in most homes, with #18 gauge stranded copper wire inside. They connect table lamps, fans, clocks, extension cords, & Christmas lights. The difference between SPT-1, SPT-2 and SPT-3 rests with their protective exterior, each having heavier construction than the previous number. All are rated for a 7 amp load. Electricians like "zip cord" because the parallel wires can easily be snipped and pulled apart (unzipped) to quickly wire a plug or lamp.
---spt-3: is the newest cord , it has the thickest thermoplastic insulator, and has been the required size for most consumer electric items since the 1980's.
---spt-1: has the thinnest exterior and was introduced around the 1950's as the modern replacement for the twisted-pair cloth+rubber cords of the 1920's. Although spt-1 is still sold on spools, it has been gradually phased out for most consumer lighting because UL lab tests showed it prone to wear when people abused it (running under carpets, extreme abrasion, etc.). SPT-1 can still be found on many light-duty Christmas sets. .......... written by dave from austin, Texas
What else can I help you with?
How much is the potential difference between the terminals of a connection wire?
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.
What constitutes an electric current in a wire?
An electric current in a wire is the flow of electric charge, typically carried by electrons, through the wire. This flow of charge is driven by a voltage difference, or potential difference, between two points in the wire.
Why does the current flow through wire?
Current flows through a wire when there is a difference in electric potential between two points. This potential difference creates an electric field that drives the flow of electric charge (current) through the wire.
What is the relationship between the current flowing through a wire and the potential difference across it?
The relationship between the current flowing through a wire and the potential difference across it is described by Ohm's Law. Ohm's Law states that the current (I) flowing through a wire is directly proportional to the potential difference (V) across it, and inversely proportional to the resistance (R) of the wire. Mathematically, this relationship is represented as V I R.
What is the difference between a live wire and a neutral wire in an electrical circuit?
A live wire carries electrical current to the device, while a neutral wire completes the circuit by returning the current to the power source.

Is there a difference between black wire and red wire?
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
Electrons are made to flow in a wire when there is?

What is the difference between a black wire and a white wire in electrical wiring?
The difference between a black wire and a white wire in electrical wiring is that the black wire is typically used as the hot wire to carry electrical current, while the white wire is usually used as the neutral wire to complete the circuit and return the current to the power source.
What is the difference between awg and swg?

What constitutes an electric current in a wire?
An electric current in a wire is the flow of electric charge, typically carried by electrons, through the wire. This flow of charge is driven by a voltage difference, or potential difference, between two points in the wire.
What is the difference between a 1 wire and 2 wire alternator?
2 wire has a live wire to energise the field where as the single wire alternator self energises and does not need the powered feed.
