Let's understand Current, Drift Velocity and Current Density.

Assalamualaikum guys.

This entry would like to help you to understand more on the concept of  electric current, drift velocity, and current density.

The explaination  in this video is at the AP Physics level.

Current, Drift Velocity and Current Density

We hope you'll understand and make your understanding regarding this subtopic deeper.

InsyaAllah.

Simple Simulation

Assalamualaikum and good morning =)
Today we will share with all of you about an interesting simulation..let's get it!!!

This simulation is about the relationship between Voltage,Current and Resistance.
You can get this at :

Physics Jokes.

Assalamualaikum guys!

Some people assume that physics seems hard to understand.Maybe yes or maybe not at all.

Today,let's have some jokes on Physics.

JOKE 1.

"A neutron walked into a bar and asked, "How much for a drink?" The bartender replied, "For you, no charge." 

JOKE 2.

" Q: What did one quantum physicist say when he wanted to fight another quantum physicist?
  A: Let me atom."

JOKE 3.

 Two atoms were walking across a road when one of them said, "I think I lost an electron!" "Really!" the other replied, "Are you sure?" "Yes, I 'm absolutely positive." 

JOKE 4.

When a third grader was asked to cite Newton's first law, she said, "Bodies in motion remain in motion, and bodies at rest stay in bed unless their mothers call them to get up."

Simulation on Ohm's Law

Assalamualaikum guys.

Today's post,let's focus on Ohm's Law.

Ohms law states that, in an electrical circuit, the current passing through a conductor between two points is directly proportional to the potential difference(i.e. voltage drop or voltage)across two points,and inversely proportional to the resistance.

Here, I found a web simulation on Ohm's Law.

We would like to invite you to surf this web.

If you wish to directly learn Ohm's Law from the simulation,

 We hope you learn and enjoy it.

Happy learn!

Simple Note For Lecture Class

Electric current      

i = dq/dt

Current density       

J = i/A        (A/m²)

      Drift speed           

J = (ne)v_d

Resistance             

R = V/I    , R = ρL / A

         

Resistivity             

ρ = E/J

Conductivity           

σ = 1/ρ

Ohm’s law

A given device (conductor, resistor, or any other electrical device) obeys Ohm’s law if its resistance R, as V/i, is independent of the applied potential difference V. A given material obeys Ohm’s law if its resistivity, is independent of the magnitude and direction of the applied electric field E.

A Microscopic View of Ohm’s Law

resistivity of metal , ρ = m / e2nT

Power in Electric Circuits

       P = IV = I²R = V²/R

Semiconductors are materials that have few conduction electrons but can become conductors when they are doped with other atoms that contribute free electrons.

Superconductors are materials that lose all electrical resistance at low temperatures. Recent research has discovered materials that are superconducting at surprisingly high temperatures.

Welcome all.

welcome to our blog :)

Bismillah

In the name of Allah,

Here we meet.For the first, we would like to thank Madam Farrah for giving this exciting task to be done as the assignment for Electric and Current subject.We would like to introduce the owner of this blog. 

"Shairah binti Gafar
Nurul Asyiqin binti Salman
Nik NurulHafizah binti Ismail" 

We do really hope that this small effort will give a big satisfaction for Madam Farrah and all class members.Besides that, we hope all the contents would help some people who search for information on Physics.

At last,we really hope that you would like to follow this blog.

Weheee:D

 Lot's of heart,
cucunewton.
