3. THE LAW OF KIRCHHOF Law I KCL – Kirchhoff curent law Total Current:
If the current of valuable cash current positive and the direction of the arrow, so vice versa.

4. According to the law applicable II:
Law II KCL (KVL – Kirchhoff voltage law)
According to the law applicable II:
So the size of the current that current is:

5. From the equation: You can obtain a new equation that is :
Can be seen that the voltage (V) is the result of the decrease in voltage due to the burden of dialiri flow (I) that is affected by barriers (R)

6. THEVENIN THEOREMS
“If a set of series voltage source and resistor is connected with two output terminals, the series can be replaced with a series of a series voltage source open circuit Vo / c and a resistor RP”

7. Figure shows a series of networks that will be associated with an LR load.
Combination Series Vo / c and RP on the image is a series of ekivalen / Thevenin equivalent.

8. There are some extreme conditions of a series of images such as time and

9. Price is a series of conditions on the open, as though removed from the RL output terminal, thus obtained opens a series of voltage CV 0 / (see picture).
Time (images) are a series of conditions are on the short tranision (end of the second terminal is connected directly) with the flow of short Hubung IS / C of

10. THE NORTON THEOREMS
“If a set of series voltage source and resistor is connected with two output terminals, the series can be replaced with a series of parallel flow from a source IN a short series of preparatory and a conductor GN ”

12. In the image above a series of equivalent Norton portrayed with a combination of a parallel between the source and flow in a konduktan GN (see figure d).

13. If this series will be burdened with a load konduktan LG, the two rates, namely and extreme. Price (or ( or LR = 0) conditions are on the short Hubung flow and short Hubung IS/C is the same as the IN.

14. Thus for the series of Norton equivalent effect:
While the price of GL = 0 (or L = ¥ ) is a series of conditions in the open, where that v0 / C voltage is a series of open.
Thus for the series of Norton equivalent effect:
