Right Hand Rules; 1 and 2

RHR #1 is for conductors and it used with conventional current (+ to -). To execute the right hand rule you simply point your thumb in the direction of the current and curl your fist. The direction which your fingers are pointing towards is the direction of the magnetic field. 

RHR #2 is used for coils and conventional current. You wrap your hand around the coil with your fingers pointing in the direction of the current and your thumb should then point to the direction of the magnetic field B, or N (north). 

ooo00o0o0o another haiku;

Birds and sharks have died,

due to Earth's magnetism.
Humans feel nothing. 

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.

Introducing Ohm and Kirchhoff

Today, I learned about Ohm's Law in Physics class. Mylifeisaverage
ooOOOoooOoo I feel like a scientist,
but all my discoveries are from the internet.

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them.^[1]

The mathematical equation that describes this relationship is:^[2]

where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.

Kirchoff;

(Series Circuit)

The total voltage is the sum of the voltage on each component. eq 1: V0 = V1+ V2 + V3 +...+ Vn(In this case, VT = V1+ V2) The total resistance is equal to the sum of the resistance on each component. eq 2: R0 = R1 + R2 + R3 +...+ Rn(In this case, RT = R1 + R2) The total current is equal in every component. eq 3: I0 = I1 = I2= I3= I4 =...= In(In this case, IT = I1 = I2)

Section 2. Parallel Circuit.                                                                                     The total voltage is equal in every component. eq 4: V0 = V1= V2= V3 =...= Vn(In this case, VT = V1= V2)The resistance is equal to the sum of resistance on each component divided by the product of resistance of each component. eq 5: 1/R0 = 1/R1 + 1/R2 +...+ 1/Rn(In this case, 1/RT = 1/R1 + 1/R2) The total current is equal to the sum of current in each component. eq 6: I0= I1 + I2 + I3 + I4 +...+ In(In this case, IT = I1 + I2) SOURCE

Favourite Roller Coaster Design

I am somewhat an adrenaline junkie and i enjoy going on roller coasters immensely. My favourite roller coaster at Wonderland is the Behemoth. It made its debut in May of 2008, it's approximately 1620m long and 70m high. It goes 125km/h and the entire ride is 3 minutes and 10 seconds of pure mind-numbing epicness.
And it looks like this: 

oooo00o0o00o so beautiful

Um, here's a haiku;


When you're going down
at an incredible speed,
You regret eating.

From Batteries to Circuits

Today, we did an activity with batteries, voltmeters and amp meters. Essentially, we built simple circuits using batteries and a light bulb. The batteries converted its chemical energy into electrical energy; which made the light bulb(load) light up.
wow, this is a really short post.

so here's a haiku;

so far I've been through
three lessons in physics class.
am i Hawking yet?

Energy Ball Experience

During my first Physics class I was arbitrarily put into a group of four and given an energy ball along with a few questions. We were told to answer the questions and during the process of which we learned about circuits and whatnot. There were two metal plates on the energy ball and by touching both plates simultaneously we were able to complete the circuit and the ball would subsequently light up and hum.


I felt somewhat special when I was the only one able to complete the circuit using my face and ear. My single talent in life turned out to be an uncanny ability to pass electrons through my body. I'm an above-average conductor. wow. 


At the end of the class Mr. Chung challenged the class to make a parallel circuit that would be able to complete the circuit of both energy balls. And the aforementioned circuit should be able to turn either one off while the other one remained on. So we formed a circle with a line of people in the middle and held only pinkies to avoid lawsuits or something. After that we assigned a switch,tested it out and successfully completed the task.


I think the energy ball didn't work on Mr. Chung because he wasn't actually touching the ball. Or maybe he has callouses on his fingers and they acted like insulators. Or maybe he's just not cut out for completing circuits.

I dunno.
