Series Parallel Circuit Examples. Series parallel circuit and equivalent circuit. Figure 4 circuit diagram for example 1.
There are two basic ways in which to connect more than two circuit components. It should be noted that the subscript labeling those little numbers to the lower right of the letter r are unrelated to the resistor values in ohms. Here we have three resistors labeled r 1 r 2 and r 3 connected in a long chain from one terminal of the battery to the other.
Since r2 and r3 are in parallel req r3 r3 r2 r3 10 40 10 40 8ω r e q r 3 r 3 r 2 r 3 10 40 10 40 8 ω.
The current paths through r 2 and r 3 are then tied together again and current goes back to the negative terminal of the battery. Draw the equivalent circuit as in figure 2 b with r eq r 2 r 3. The current paths through r 2 and r 3 are then tied together again and current goes back to the negative terminal of the battery. You may also read.
