SUMMARY

This discussion focuses on the relationship between voltage drop and current in circuits containing mixed resistances, specifically those configured in both series and parallel. It is established that elements in series maintain the same current, while elements in parallel share the same voltage drop. The application of Kirchhoff's laws is essential for analyzing complex circuits, and the node-voltage method is recommended for solving these types of problems effectively.

PREREQUISITES
  • Understanding of series and parallel circuit configurations
  • Familiarity with Kirchhoff's laws
  • Knowledge of voltage drop and current concepts
  • Proficiency in the node-voltage method for circuit analysis
NEXT STEPS
  • Study Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL)
  • Explore the node-voltage method in detail
  • Learn about Thevenin's and Norton's theorems for circuit simplification
  • Practice solving mixed resistance circuits with varying configurations
USEFUL FOR

Electrical engineering students, circuit designers, and anyone involved in analyzing or designing electrical circuits with mixed resistances.

When there is a current of mixed resistances (like parallel and series together), how do voltage drop and current relate throughout the circuit?
 
Physics news on Phys.org
Elements in series always have the same current, and elements in parallel always have the same voltage drop. You just need to take care to determine whether two elements are actually in series/parallel; not all elements have this sort of relationship in every circuit.
 
Sounds like a homework question to me.
For complicated relationships between elements, you need more complicated rules ... like kirchhoffs laws.

Usually I like to solve circuits using the node-voltage method.
