Spark Plug Wires? Remove them 1 at a time from the spark plug to the distributor or the ION pack, remove and replace the spark plug, add the new spark plug wire from the newly added spark plug to the distributor or ION pack.
Physical. The metal wire is still a metal wire after the change.
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
When ever a wire is changed, change it by the same type, rating or capacity of wire.
Change one wire at a time. Take the wire from the distributor then the spark plug end, replace with wire of same length. As you do this compare wire lengths and you will be able to change them without any trouble. BE SURE THE SPARK PLUG END BOTTOMS WHEN YOU INSTALL IT OR YOU WILL GET A MISS IN THE FIRING.
I order to do this all the wire need to be replace with three wire.
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
A circuit breaker does not have a wire fuse in it.
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
When ever a wire is changed, change it by the same type, rating or capacity of wire.
No, you don't have to change the wire, but the wire supplied with most all-in-one systems is quite thin. If you are running the wire for long lengths, you might consider upgrading to a thicker wire to minimize the signal loss.

A: It is a transformer that has one or more leads wire output so switch can be used to change the output voltage from a reference wire.
