About Me

I blog about my daily learnings in Physics class and I also throw in a haiku here and there.

Concept Map + 10 Things You Need to Know About Electricity


1. The symbol for Current is I, the unit for current is Amperes, the equation for current is I = Q/t
2. Conventional current is the direction of current from the positive terminal to the negative terminal, unlike electron flow, which is from negative to positive.
3. DC/direct current Vs. AC/alternating current
4. Series Vs. Parallel circuits
5. Ohm's Law
6. Kirchoff's Law
7. R is the symbol for Resistance, resistance is measured in Ohms, the equation for resistance is; R = V/I
8. P = IV where P represents power and is measured in joules
9. How to read resistors and graphs
10. How to draw complex circuits with voltmeters and ammeters

um, yeah, haiku;


Electricity,
is a really long word. It
has five syllables.
