Lecture 4
2. Resistive circuits
Objectives
• To solve circuits ( find currents and voltages)
• To learn about Resistors in series and in parallel and ho wto find the
equivalent
• Network analysis using series and parallel equivalent
• Apply voltage division and current division principles
2.1 Resistances in Series and Parallel
Parallel Resistances
For 2 resistances in parallel
Example : find the equivalent resistance
Example: Find Req in each
2.2 Network Analysis by Using Series and Parallel Equivalents
2.3 Voltage-Divider and Current-Divider Circuits
