Ohm's vs Kirchoff's Law

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.
Given Ohm's triangle....

V= IR

I = V/R

R= V/I

Kirchoff's Law implies that At any junction in an electrical circuit, the sum of currents flowing into that junction is equal to the sum of currents flowing out of that junction. 

or

The algebraic sum of currents in a network of conductors meeting at a point is zero.

Series Circuit:

Current:

It = I1 = I2 = I 3...=In  

 Potential Difference:

Vt = V1 + V2 + V 3...+Vn

Resistance:

Rt =R1 + R2 + R 3...+Rn

Parallel Circuit:

Current:

It = I1 + I2 + I 3...+In

Potential Difference:

Vt = V1 = V2 = V 3...= Vn

Resistance:

1/Rt = 1/R1 + 1/R2 + 1/Rt3...+1/Rn

Top 3 Roller Coasters

1. The Kingda is an exciting roller coaster because it is the tallest roller coaster at 456 feet! It is located in Six Flags  The top speed on this coaster is 128mph. It's a simple coaster with one giant hill.

2. The new Formula Rossa is my next favourite because it currently holds the record for fastest steel roller coaster at 149.1 mph! It is a ferrari themed coaster so it goes with the record title.

3. This next coster features the tallest vertical loop at 145 feet. It's called the Superman: Krypton Coaster. It is locataed in Six Flags Texas.

Electron Flow vs Conventional Current

Current is a flow of negatively charged electrons repelling one another. It use to be thought that the current flow was moved from the positive end to the negative end, but studies show it's actually the opposite.

Electron Flow
An electron flow is a movement of electrons in a circuit. The electrons are moving
from the negative to the positive side of the circuit. 

Conventional Flow

In a conventional flow, the electrons are moving from the positive to the negative side of the circuit.

Energy Ball

Last Friday, we were able to run tests on a ping pong shaped object that had a circuit inside with a light bulb. In a group of four, we were given questions to answer relating the circuit. Questions relating to how the light bulb would light and would it light with more than one person connecting the circuit. The "ping pong ball" had two metal strips on the side, and in order to light the bulb, you had to touch both strips. Our fingers acted like a conductor. The light bulb will then light up, and make a noise.

We then had one person touching one strip, the next person touching the other person's hand, and another person touching the hand of the last person, until the 4th person touched the third person's hand with one hand and the remaining metal strip with the other hand. This allowed the circuit to be complete.

Our big next task involved the whole class to work together. Our objective was to make a parallel circuit with two light bulb and a switch to turn off one light bulb when needed. In order to do this we connected people in a circle with the light bulb on opposite ends. Then had a line of people in between the light bulb. A parallel circuit is like having two circuits that are connected to one another.

In a series circuit, if a component of the circuit burns out, then the rest will not work and the circuit will not be complete. If a component in the parallel circuit burns out, the rest will still work.
