What color wire is always used to carry electrical current? D black copper green white

## Step 1<br />In electrical wiring, different colors are used to represent different types of wires. The color of the wire is used to identify its function in the circuit.<br />## Step 2<br />The black wire is typically used to carry the "hot" or live current. This means it carries the electrical current from the power source to the device.<br />## Step 3<br />The copper wire is not a color, but a material. It is used to make the wires, not to carry the current.<br />## Step 4<br />The green wire is usually used as the ground wire. This wire is used to provide a safe path for the current to flow back to the ground in case of a fault.<br />## Step 5<br />The white wire is typically used as the neutral wire. This wire carries the current back to the power source after it has passed through the device.
