Science: Resistance

 How does resistance affect current?

Resistance: resistance is about pushing back. Resistance slows down the current. 

Current: Current is how quickly the electrons move.

Voltage: Is how much energy the electrons are carrying.

- In series: In a series circuit the electrons go/pass through one path.

-In parallel: In a parallel circuit the electrons split into the different pathways/branches.  

- The image on the left shows the difference between having a resistor and not having one/

-When there is a resistor the resistor slows down the currents.  

-More resistance means the currents are slower.

-less resistance means that the currents are faster.

To differentiate between the two: 

If you look at the series circuit with the resistor you will notice that the light is very less compared to the parallel circuit, which has more energy because there is nothing slowing down the electrons.

Electricity

 Circuits:

1. Series Circuit:

2.Parallel Circuit: 

3. What is the difference between a series & parallel circuit?

- Series: In a series circuit all electrons pass through one path. 

- Parallel: In a parallel circuit the electrons split ways, and go down to the different branches.

4. What is Voltage and current in a circuit?

- Voltage is how much energy the electrons carry. 

- Current is how fast and slow the electrons move.

5. Explain why a string of Christmas tree lights would be parallel no series?

- Christmas tree light will not be series because the electrons will need to split off to different branches(lights) in the light.

Physics

 Current Electricity:

1. What is the particle that moves in a wire? 

The particle that moves in a wire are electrons. Electrons move from the negative end to the positive end.

2. If there is a high current in a circuit what does it mean?

If the current circuit flow gets too high it will melt the fuse. They are burning/ moving too fast. 

3.How does electricity work to heat up a stove?

Electric energy transforms into heat energy and heats up the stove.

4. Where is DC electricity used? Where is AC electricity used?

- Direct Current(DC) is used in charging batteries, etc.

- Alternating Current(AC) is used in plugs, lights, etc. 

Physics

 Static electricity

1. The particles that make up everything are Protons, Electrons and Neutrons. 

- Protons have Positive charge.

-Electrons have negative charge.

-Neutrons have no charge.

2. It means it wants to have the same number of positives and negative.

3. Insulator does not pass electricity. If an Insulator passes on energy it is conducting( passing on electrons). 

4. Example of static electricity.

-Rubbing a balloon on hair.

-Jumping on a trampoline.
