Magnetic flux lines

Magnetic flux is used to describe as the total amount of magnetic field in a region
The term flux was chosen because the power of a magnet seems to "flow" out of the magnet at one pole and return at the other pole in a circulating pattern, as suggested by the patterns formed by iron filings sprinkled on a paper placed over a magnet or a conductor carrying an electric current. These patterns are called lines of induction.
Although there is no actual physical flow, the lines of induction suggest the correct mathematical description of magnetism in terms of a field of force. The lines of induction originate on the north pole of the magnet and end on the south pole; their direction at any point is the direction of the magnetic field, and their density (the number of lines passing through a unit area) gives the strength of the field. Near the poles where the lines converge, the field and the force it produces are large; away from the poles where the lines diverge, the field and force are progressively weaker

Circuit Maker Practice

I tried to use Circuit Maker program and it is easy, fast, and

helps me a lot. I tried to draw one of our exercises in this program

and it takes me a only a few minutes. However I still finding some

trouble in converting a Schematic drawing to Vero board layout.

If you want to send me some links to help me converting it just comment

the links...thnx

Solving a Circuit

This is an example of a Series-Parallel circuit.

How I solve it?

1. I always check the circuit first, if it is a Series, Parallel, or Series-Parallel Circuit.
2. Then I'll find the formula for the specific circuit and write down what is missing in the circuit.
3. The total voltage, resistance for each resistor, or the current is always given in the circuit. You will usually need to find the voltage passing through the circuit, total resistance, total current, current passing through each resistor, and Power
4. Remember that different circuit has always different formula and the Series-Parallel is a combination of the two circuit.

Here's a link for the formula about the circuits.

Spreadsheets

Here's my spreadsheet about E12 Range for Series and Parallel.

I hope it helps.

Series and Parallel Circuits

Series Circuits

-A circuit composed solely of components connected in one continues path
-The total voltage is the sum of the volt drops
-And the current are the same at every point





Parallel Circuits

- If two or more components are connected in parallel their voltage is the same
across every branch and the total current is the sum of branch current

Resitor Color Code

This is a one example of a resistor.... It is a 5-Band-code
Do you know how to read it to find out what's the minimum and maximum resistance??

This is how I do it...

First I will found the tolerance band...that is the last band after the
big gap...in the picture above the color of the tolerance band is a gold.. that is plus and minus 5%

Then I look up the color code table



Then I always read it backwards....I start with the multiplier and put all the zero then the rest of the bands...

In the resistor above the multiplier is black...the multiplier is always tells you how many zero's you have in the band..... black has no zero's and don't
have to put it... then

White = 9
Orange= 3
Orange= 3

933 is the reading up to the fourth band then plus and minus it to 5% to get the minimum and maximum resistance...

5% of 933 is...46.65

Minimum: 933-46.65 = 886.35 ohms

Maximum: 933+46.65= 979.65 ohms

I hope this thing helps you...


Thnx,

Dan
