Ampacity is defined as the maximum amount of electrical current a conductor or device can carry before sustaining immediate or progressive deterioration.

Alternatively, three wires may be used, but the common conductor carries the vector sum of the phase currents, which requires a larger conductor.

Under normal conditions, a grounding conductor does not carry current.

The resistance, determined by width and thickness, of the traces must be sufficiently low for the current the conductor will carry.

There are also current probes, with cores that surround the conductor carrying current to be examined.

"The conductors held the train and carried both the man and his wheelchair up and down the stairs to the walkway."

The train's conductor carried her off the train and to a cabin, where she died soon after.

The two extra conductors in the 6-pin connection carry electrical power.

Because the outer conductor carries the reference potential for the signal on the inner conductor, the receiving circuit measures the wrong voltage.

The braid is grounded while the central conductor(s) carry the signal.
