Electricity is a flow of current (moving charges) and has to flow into and out of a circuit or other object. In automotive applications, the metal body of the car is often used as part of the negative conduit. In grounded circuits for alternating current, any connection to the ground can provide a path (short circuit, electric shock). In lightning, any object in the path of current flow, either upward or downward, may carry the flow of high-voltage charges.

What two metals are most common in electric wires?
Copper is one.
Why are two wires used to carry electric current instead of a single wire?
It takes two wires to complete a circuit. They are commonly called a positive and negative. Without a flow of electricity both in and out of an electric item, there will no be a circuit and the item will not work.
How many wires must a current have?
Current needs only one wire to flow in, but a circuit needs at least two wires to connect the source to the load.
Why is there only one wire to a desk fan?
It's probably not a single wire you're looking at. It's probably a cable containing two wires. One phase wire, and one neutral wire.
Can an electric range be powered from the same circuit as an electric dyer?
No. The two appliances usually have dedicated circuits. The range will have a two pole 40 amp breaker and be fed with a 3-C #8 copper cable. The dryer will have a 30 amp two pole breaker and be fed with a 3-C # 10 copper cable. As you can see by powering a 40 amp device from a 30 amp breaker, full operation of the range will trip the 30 amp breaker.
How many wires are there in a USB cable?
a usb cable has four wires, two for power and two for communication.
Two parallel wires carry electric current in opposite directions the magnetic forces of the two wires are?
Repulsive
Does electricity flow through wires?
Electric current flows through wires, but to transmit electric power you need two wires with a voltage between them, connected to a power source.
How audio and video signal travel bidirectional in one cable?
It depends on the architecture of the cable but the most common is multiple wires in the cable, you only need two wires at a minimum to communicate, one as a ground or base, and the other to for the signal. The devices can also take turns communicating, allowing for two wires to be enough. An example of a two wire cable is the typical headphone cable, though it is in a single direction. Four wires allow for two way communication, one set for transmit, and one for receive, which on the other end the transmit wires become receive, and the receive wires become transmit. A typical example is the Ethernet cable which your computer is most likely connected to the internet with.
What two metals are most common in electric wires?
Copper is one.
What is welding cable used for?
A welding cable is used for joining or linking up wires or cable. Welding is the process of joining two things together, and the cable is the connector.
When electric currents flow in the same direction through two wires the wires attract each other why?
magnetism
The difference between UTP cable and Coaxial cable?
A UTP cable has 4 pairs of twisted wires. In a coaxial cable, there are two conductors, one inside the other. Since they have a common center, or axis, they are called "coaxial" (co-axial).A UTP cable has 4 pairs of twisted wires. In a coaxial cable, there are two conductors, one inside the other.

What are two types of PATA data cables?
Under parallel ata, two types of ribbon cable are used. The 80-conductor ide cable has 40 pins and 80 wires Forty wires are used for communication and data, and an additional 40 ground wires reduce crosstalk on the cable. An older 40-conducror cable has 40 wires and 40 pins. the two types of cables are PATA and IDE cables which come in a 80-conductor IDE cable and a 40-conductor cable
What is weld used for?

What are the two wires inside the cable of a hairdryer made from?
Most likely insulated copper.
How many conductors are on a Serial ATA cable?
The plugs and sockets have 7 pins, however three of them are earths. Whether the three earths are carried through end-to-end is probably up to the manufacturer. So, the cable would have at least 5 wires: Two data channels with a + and - for each, plus at least 1 earth.
