Thevenin theorems states that any two of the series can be converted into an equivalent set of which consists of a voltage source thevenin (ETH) and a resistans equivalent thevenin (RTH) is in series with voltage source thevenin.
Steps to find the rope thevenin is:
1. Specify two of the series who want to search string thevenin it.
2. Determine the amount of voltage thevenin (ETH), namely the voltage between two terminals which want to search a series of rope thevenin it.
3. Specify the size of the resistans thevenin (RTH) is equivalent resistans a review / calculated from the two-terminal series who want to search string theveninnya. At the time resistans thevenin determine this, all sources should be eliminated. Voltage source into a series of short relationships and sources of flow into a series of open relationship.
4. Strand thevenin its image.
Example
Specify thevenin strand of a series that is connected to resistor R3 on the image below!
Answer:
specify the first series who want to search thevenin its rope, as the picture below:
Then specify the ETH:
ETH is the same as the voltage between the terminal R2
Determining RTH:
Eliminate all sources used in the series. Thus the voltage source into a series of short Hubung (V = 0). Series is to be:
then, its thevenin strand shown in the picture below
