Exp 2. Series-Parallel Circuits

Concept : To demonstrate the effect of the resistances in series or parallel

 

Explanation:

Series-parallel circuits, as the name suggests, are electrical circuits that combine elements of both series and parallel connections. Understanding these circuits involves recognizing how they are structured and how voltage, current, and resistance behave within them.

  1. Series Circuit: In a series circuit, components are connected end-to-end so that there is only one path for current to flow. The current is the same through all components, but the voltage across each component can vary.

  2. Parallel Circuit: In a parallel circuit, components are connected across the same two points, creating multiple paths for current to flow. The voltage is the same across each component, but the current through each component can vary.

  3. Series-Parallel Circuit Configuration: A series-parallel circuit has some components connected in series and others in parallel. This combination allows for more complex and flexible circuit designs.

 

Simulation Mode: Transient/DC Sweep

 

Simulation Parameters: Any reasonable values would work. For example:
