We say the aluminum has a higher resistivity . In a conductor the current and current density are proportional to the applied electric field. The
Crimping Tool Selection Guide. Crimpers are tools used to make cold weld joints between two wires or a wire and aconnector, such as lugs.

Crimping tools are sized according to the wire gauges (using AWG American Wire Gauge) they can accept.

Stripping the coil: Go back and check that the insulation has been stripped properly (see Figure 4 in the Procedure): on each axle the top half (lengthwise) of the copper wire should be bare. Removing too little or too much insulation will make the wire fail to spin. Coiling the wire: Make sure the wire is coiled as neatly as possible so that ...
When wiring a 2way switch, this image on the left will show how the connections should actually look when all connections are made. Take notice of the ground wire.
