Your Questions About X1

Paul asks…

How do I connect an electrode to my circuit wire?

I want to connect my copper wire to my electrode (so that electric current will flow to it from my voltage source). Can I simply just solder the wire onto the electrode? Or should I wrap it around tightly? Or something else entirely?

The electrode is a metal plate 1″x1“.

Thanks! Doing an extra credit project.

Administrator answers:

Whatever makes a good connection. It depends on the material of the electrode. And of the solution. Will copper have an adverse reaction with the chemicals? Will solder?

Wrapping it tightly will work, but it will work loose in a bit. Soldering is good, if the chemical it will be in will not be a problem.

Drill a hole and put in a self-tapping screw and put the wire under the screw.

Make a small fold in the electrode and crimp the wire in the fold.

Administrator answers:

For proper readings a mechanical connection is needed. Just wrapping the wire is not enough, you will have voltage, wattage, and amperage fluctuation. Also it will cause heat…

Yes drilling the plate and connecting with a screw is a solution usually found in grounding practices. Soldering is the preferred method, sand the wire and the plate where the wire will be connected. Use flux on both the wire and plate. Tint the wire, and bond a bit of solder to the plate. Now solder the wire to the plate. Allow to cool and check for a cold joint (cracking, discoloration).

You didn’t state the thickness of the the plate, if its thin you shouldn’t have any problem. But if it is to thick you may have to heat with an hair dryer up to a torch to bond a bit of solder properly.

John asks…

How to mirror vector A relative to a plane perpendicular to vector X?

For example in R3, vector A(a1,a2,a3) is mirrored to a plane perpendicular to vector X(x1,x2,x3). What is the vector resulted from this mirroring process ?
the plane perpendicular to Vector X, is used as the mirror.

Administrator answers:

Let’s assume that ||X|| = 1 (if not, divide X by its norm; it doesn’t alter the plane or A), then the component of A in the direction of X is:

A(X) = (A,X)X

Where (…,…) is the inner product. Notice that A(X), being collinear with X, is also orthogonal to the plane, and its mirror image is ?A(X). Now, the mirror image of A in X is given by adding to A twice the mirror image of A(X):

M(A,X) = A ? 2A(X)

Where M(A,X) is the mirror image of A. This will be a lot clearer if you draw a picture.
