The most likely explanation is that the equipment used to stimulate the nerves uses a DC voltage to do so.
You can get the positive and negative wires for a class project at a store that sells the Physics apparatus.
usually, positive wires have a blue rubber coating, whereas negative wires have a red rubber coating.
All electrical components have positive and negative wires to complete the circuit.
The positive wires for IAT sensor on a dodge ram are the red ones. The black wires are are ones that serve as the negative cables.Ê
A 220 vac circuit has 2 hot wires and a neutral. The neutral stays at 0 volts and the hot wires vary between positive and negative. When one is positive, the other is negative.
Positive is normally red and negative is normally black or green. Test them with a volt meter to be sure.
The negative wire is the one with this symbol on the battery. (-) Positive is (+)
Yes they do - it means the long stem is positive and must be connected to positive wires and the short stem to negative wires
red is positive and black is neutral...if the wires are red and black.
Dark blue is positive and light blue negative on right side and brown positive and yellow negative on the left.
If you mean the battery wires look at the battery terminals the positive terminal is always the biggest diameter
Positive and Negative Terminals.
