We will hav to use tools from both of the previous units, series circuits and parallel circuits. In this unit we also learn a new circuit analysis technique: Source conversion. We can use this tool to convert a current source to a voltage source. Problems 1-15 are for primary practice. You should feel comfortable with your ability to solve all ...
The article discusses series-parallel circuit, which are combinations of series and parallel resistor arrangements, explaining their analysis using equivalent resistance calculations and Kirchhoff’s laws. ... Obviously, the current through R 1 is now greater than normal, and again power dissipation might present a problem. Fig.9: Short ...
Notes: The answers to this question may seem paradoxical to students: the lowest value of resistor dissipates the greatest power.Math does not lie, though. Another purpose of this question is to instill in students’ minds the concept of components in a simple parallel circuit all sharing the same amount of voltage.. Challenge your students to recognize any mathematical patterns in the ...
A circuit breaker in series before the parallel branches can prevent overloads by automatically opening the circuit. A 15 A circuit operating at 120 V consumes 1800 W of total power. P = VI = (120 V)(15 A) = 1800 W. Total power in a parallel circuit is the sum of the power consumed on the individual branches.

Notes: Rules of series and parallel circuits are very important for students to comprehend. However, a trend I have noticed in many students is the habit of memorizing rather than understanding these rules. Students will work hard to memorize the rules without really comprehending why the rules are true, and therefore often fail to recall or apply the rules properly.
