Why can wire sizes be smaller when higher system voltages are used?
It has to with the fact that when voltages go higher the current goes lower. The lower the current a device draws, the smaller the wire size needs to be to carry that current.
Does earthing wire carry current?
The earthing wire does not normally carry current.
Does thin wire carry more current than thick wire?
No. The larger wire can carry more current.
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
Does neutral wire carry voltage in a closed circuit?
The ground wire should carry no current at all, it is there in case of a short circuit to carry the (short circuit) current back to the breaker panel to trip the breaker. The neutral will carry the unbalanced load current between the 240 volt legs. e.g. L1 and N (neutral) 120 volts the load draws 8 amps. L2 and N (same neutral) 120 volts the load draws 12 amps. The difference between the two amperages is what the neutral will carry 12 - 8 = 4 amps.
What winding of a current transformer carry more current?
Primary winding carry more current. We measure the current in one single wire, so no of turns are 1, in secondary the no of turns are higher. so, obviously it has higher voltage then this wire. so, finally as per the transformer rule the secondary carry lesser current than primary.

What is the aluminum wire equivalent to?
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.

The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
What wires carry current?
A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R

Electric current in a metal conductor is carried by?
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.
What gauge wire do you need to carry 240 volts 1000 yards?
Wire sizes are governed by the amperage the wire is to carry. To answer this question the load current is required.
What part of a circuit is the wire cable or switch?
Wire is the transition material used to carry the electric current; the switch is the controller of that current.
Can stranded 8 SWG GI wire be used for motor earthing?
The size of grounding wires is dependant upon what the motor current category the motor fall into. The higher the motor amperage is, the higher the fault current will be so the larger the conductor size has to be to carry the fault current.
