Analysis of Combination CircuitsExample 1Example 2Developing A StrategyThe basic strategy for the analysis of combination circuits involves using the meaning of equivalent resistance for parallel branches to transform the combination circuit into a series circuit. Once transformed into a series circuit, the analysis can be conducted in the usual manner. Previously in Lesson 4, the method for determining the equivalent resistance of parallel are equal, then the total or equivalent resistance of those branches is equal to the resistance of one branch divided by th..See more on physicsclassroom[PDF]

The basic technique used for solving dc combination-circuit problems is the use of equivalent. circuits. To simplify a complex circuit to a simple circuit containing only one load, equivalent. circuits are substituted (on paper) for the complex circuit they represent.
Example Problem #1 on Combination Circuits
This circuit is composed of 3 'elements' connected in series: the group of parallel resistors between A and B, the single resistor R3, and the group of parallel resistors between C and D. First, we will find the equivalent resistance between A and B. Here, we have two resistors, R1 and R2, connected in parallel. Using the formula for resistors connected in parallel:

Rt = R1+ R2 + R3 . The volt drops across all resistors must add up to the source voltage. VSource = VR1 + VR2 + VR3 . In parallel: Voltage remains constant throughout the branches. Vsupply = VR1 = VR2 = VR3 . The sum of the branch circuit currents adds up to the total line current.[PDF]

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 1,800 W of total power. P = VI = (120 V)(15 A) = 1,800 W. Total power in a parallel circuit is the sum of the power consumed on the individual branches.

Learning to mathematically analyze circuits requires much study and practice. Typically, students practice by working through lots of sample problems and checking their answers against those provided by the textbook or the instructor. While this is good, there is a much better way.
Resistors in Series and Parallel - Resistor Combinations
Resistor circuits that combine series and parallel resistors networks together are generally known as Resistor Combination or mixed resistor circuits. The method of calculating the circuits equivalent resistance is the same as that for any individual series or parallel circuit and hopefully we now know that resistors in series carry exactly the same current and that resistors in parallel have exactly the same
Resistors in Circuits - Problems – The Physics Hypertextbook
A kitchen in North America has three appliances connected to a 120 V circuit with a 15 A circuit breaker: an 850 W coffee maker, a 1200 W microwave oven, and a 900 W toaster. Draw a schematic diagram of this circuit. Which of these appliances can be operated simultaneously without tripping the circuit
