So I'm gonna have a prac assessment on testing the electrical conductivity of some substances (second dot point on chemical earth). So I have a few questions and I'm terrible on electrical stuff, would really appreciate if anyone could help me out.
1. Does it matter where I place my ammeter, both in circuit drawings and the prac? I was thinking of putting it after the testing material, since the ammeter could measure if any current has been passed through the material. If this is true, then which way does the current flow (so I could draw the ammeter)
2. We're also supposed to construct a table to record the data. I was thinking of having the subheadings; Substance name | metal, metalloid, or semimetal? | Amperes (A) | Conductivity (S/m) |
Are the units for the conductivity correct? ie. Siemens/meter, s/m? And this is the inverse of the resistance right, so basically to calculate this, I would just need to divide the Amperes by the voltage right?
Thankyou so much for answering these questions
