There is a current through the lamp only when the potential difference across it. 5 Wiring lamps in series and in parallel 5. In this interactive object, learners work 12 problems dealing with dc circuit analysis. 4 Multiwire Branch Circuits. Parallel and series circuit electricity worksheet with answers will help learners gain a better understanding of the concept and applications of series and parallel connections in electricity. Parallel subsystems have a common input and their outputs are summed together. Series/Parallel RLC circuits R L C i R L C V iR iL R VC V iC L I 0V * A series RLC circuit driven by a constant current source is trivial to analyze. The (left or right channel) output of a typical CD player can be modeled as a voltage source that is able to produce voltage between 5V and +5V and currents between 10mA and +10mA without distorting.
