The amperage capacity of a wire is determined by the cross sectional area of the wire.
Another Answer
Electrical conductors are expressed in terms of their cross-sectional area. In Europe, for solid conductors, this is expressed in square millimetres. Stranded conductors are expressed in terms of the number of strands, and the diameter (in millimetres) of each strand, expressed in the format A/B (where A = number of strands, and B = diameter of strand) -from which the total area, in square millimetres can be determined.
In North America, the cross-sectional area is expressed in circular mils (round conductors) or square mils(rectangular conductors). A 'mil' is one-thousandth of an inch. A 'circular mil' is the diameter of a conductor, expressed in mils, squared -so it is not really a measure of area (as it doesn't take pi into account), but a figure that represents an area.

What is the difference is 22D and 22M for connector contact size ratings?
22 will handle wire sizes 22-26 22D will handle wire sizes 22-28 22M will handle wire sizes 22-24
In an IEC-320 plug which wire carries electrical voltage?
the hot wire carries the electrical voltage
Can 2 lengths of 14 Ga romex be used to make a 30 A circuit?
No, electrical wires can only be run in parallel on wire sizes 1/0 and larger. To supply a load of 30 amps you will need #10 wire and a 30 amp breaker.
What are the three electrical guantities?
The three electrical quantities are current voltage and resistance. Current is measured in amperes (A) and is the rate at which electricity flows through a conductor. Voltage is measured in volts (V) and is the electrical force pushing the current through the conductor. Resistance is measured in ohms () and is the opposition to the flow of current. Current - measured in amperes (A) Voltage - measured in volts (V) Resistance - measured in ohms ()
A jumper wire should be used to bridge the electrical ground across?
A jumper wire should use to bridge electrical ground across?
How do you measure Electrical wiring diameter in the United Kingdom?
Wire diameter is measured in millimetres (mm)
What size copper wire is equal to 0 aluminum?
Copper wire gauge sizes are not equivalent to aluminum wire gauge sizes. The gauge sizes for copper and aluminum wires are different due to their differing electrical conductivity properties. It is not possible to directly convert a copper wire size to an equivalent aluminum wire size.
How do you measure electrical current flow in a copper wire?
Electrical current flow in a copper wire is typically measured using an ammeter, which is connected in series with the wire. The ammeter measures the flow of electrons in the wire and displays the current in units of amperes (A). Make sure to set the ammeter to the appropriate range before taking the measurement.
How to measure Electrical UG power cable sizes?
All wire is sized by the amount of current that they can safely carry.
Why is a resistor called so?
I resistor is called so because it provides electrical resistance (measured in ohms). Electrical resistance describes how an electrical conductor (a wire) opposes the flow of an electrical current (flow of electrons). To overcome this opposition a voltage (a energy) must dropped (used) across the conductor (wire).
Is copper wire measured in circular mills?
Yes, copper wire can be measured in circular mils, which is a unit of area used in the electrical industry to specify the cross-sectional area of a wire. One circular mil is equal to the area of a circle with a diameter of one mil (1/1000 inch).
Is there a direct correlation between increase in coil wraps and electrical resistance of a guitar pickup?
There is a direct relationship between the length of wire (thus the number of times the wire is wrapped) and the electrical resistance of the guitar pickup, measured at the two output terminals.
What is the electrical pressure that causes electrons to flow?
Voltage, measured in volts, is the electrical pressure that causes electrons to flow in a circuit. Voltage is what pushes electrons through a conductor, such as a wire, and is necessary for the flow of electrical current.
What term is used to refer to the process of electrical discharge and the flow of electrical activity?
The term used to refer to the process of electrical discharge and the flow of electrical activity is "electric current." It is the flow of electric charge through a conductor, such as a wire, and is measured in amperes (A).
Electric current flows in a wire which is opposed by what?
Electric current flowing in a wire is opposed by electrical resistance. This resistance is caused by factors such as the material of the wire, its length, and its cross-sectional area. It results in the conversion of electrical energy into heat.
What do you call an electrical wire that is not insulated or covered?
The electrical terminology of a wire with no insulation on it is a bare wire.
What is electrical onductance measured in?
Electrical conductance is the reciprocal of resistance and is measured in siemens (symbol: S).
