Concept Map and 10 Must Knows!

Concept map, what is it really? To me, it looks like a bunch of points all linked together some how. I find that part of it really confusing, however, it does have a major advantage; the concept map shows the connections and relations between different points/concepts. When we're studying, we always want to relate things and group them together to make it all easier to remember, and comprehend, but is this technique really for you? Perhaps not, unless you're a visual learner like me. I've never actually tried this technique but I am about to, and hopefully it'll end off as a new friend.

10 Must knows!

1. Series Circuit: A single-path circuit with flow of electrons.

2. Parallel Circuit: A multi-path(divisions) circuit with flow of electrons. :]

3. Electric Current: The flow of electricity through a conductor(rate of flow). Measured using an ammeter.

4. Electric Charge: Symbolized by (Q)and is the charge of electrons measured in Coulombs (C). The charge of an electron is approximatively 1.602 x 10^(-19)C. However since it is usually measured in Coulombs, each coulomb = 6.25 x 10^(18) electrons.

5. Conventional Current: Assumes that the current flows out of the positive terminal and flows towards the negative terminal. Contradicts electron flow.

6. Electron Flow: Assumes that the current flows out of the negative terminal and flows towards the positive terminal. Contradicts conventional flow.

7. Power, Energy, Voltage: The three main units that make up most equations and is required to make most calculations.

8. Ohm's Law: R=V/I, V=IR, I =V/R

9. Kirchhoff's Law:

Series:

Current:
It=I1=I2 =I3...=In

Potential Difference:
Vt=V1+V2+V3...+Vn

Resistance:
Rt=R1+R2+R3...+Rn

Parallel Circuit:

Current:
It=I1+I2 +I3...+In

Potential Difference:
Vt=V1=V2=V3...=Vn

Resistance:
1/Rt=1/R1 + 1/R2 + 1/R 3...+1/Rn
