      Solutions to the problems in Circuit Theory 1. We have the circuit on the right, with a driving voltage ... A two-pole circuit such as this one (a Thevenin equivalent circuit) delivers ... voltage source is 10 Ω in series with a parallel combination of 20 Ω and (10+10) Ω. The total resistance is easily seen to be 20 Ω.

      Series-Parallel Circuits • Series-Parallel circuits can be more complex as in this case: In circuit (a) we have our original complex circuit. In circuit (b) we have resistors R 1 and R 2 combined to get 13.2Ω. R 4 is in series with the newly combined R 12 and their added value is 51.2Ω. And now (c) we are left with R 124 in parallel with R 3.

      need to be in parallel. This is because of the nature of series and parallel circuits. In a parallel circuit, the potential difference is always the same, but the current of the circuit is split between the multiple paths. Thus, if we were to try to connect an ammeter in parallel, its presence would in fact

      Series and Parallel Resistive Circuits The configuration of circuit elements clearly affects the behaviour of a circuit. Resistors connected in series or in parallel are very common in a circuit and act as a voltage or current divider. We use Kirchhoff's laws to understand the extent of these configurations and to analyze resistive circuits.
