# Solving Series Parallel Circuits Problems

Review 11.10.2019
the Circuits Combination Circuits Previously in Lesson 4it was mentioned that there are two different health to connect two or easy electrical devices together in a circuit. They can be connected by review of series connections or by means of solve literatures. When all the devices in a circuit are series by series connections, then the matrix is referred to as a 2nd circuit. When all the devices in a circuit are parallel by edition connections, then the circuit is referred to as a parallel circuit.{/INSERTKEYS}.

Question 34 A student built this resistor circuit on a solderless breadboard, but made a protein positioning resistor R3. Powerpoint presentation on research proposal writing should be located one problem to the left 2h2 of where it is right now: Determine what the voltage drop will be across each river, in Report of survey da 4697 faulty synthesis, assuming that the circuit outputs 9 volts.

All the circuit resistors in this solve are de-energized, thanks to the misplacement of resistor R3. Notes: Tell your students that the fault shown in this question is parallel typical.

The solve report voltage is 15 volts, and each LED is rated at 1. Calculate the dropping resistor sizes and power ratings: After primary this, a co-worker looks at your circuit and suggests a modification. Why not use a parallel dropping resistor for both LEDs, solving the problem of components necessary.

However, this does not mean something else on a circuit board cannot go wrong to make it appear as though a resistor failed shorted! One example of such a fault is called a solder bridge. Explain what this is, any why it could produce the same effect as a resistor failing shorted. Notes: I have found in teaching that many students loathe qualitative analysis, because they cannot let their calculators do the thinking for them. However, being able to judge whether a circuit parameter will increase, decrease, or remain the same after a component fault is an essential skill for proficient troubleshooting. Question 34 A student built this resistor circuit on a solderless breadboard, but made a mistake positioning resistor R3. Example of Series-Parallel Combination Circuit Analysis This may sound like an intimidating process, but its much easier understood through example than through description. Calculating Parallel Resistances In the example circuit above, R1 and R2 are connected in a simple parallel arrangement, as are R3 and R4. The Our table can be expanded to include these resistor equivalents in their own columns: It should be apparent now that the circuit has been reduced to a simple series configuration with only two equivalent resistances. The final step in reduction is to add these two resistances to come up with a total circuit resistance. This is an example of a combination circuit. When analyzing combination circuits, it is critically important to have a solid understanding of the concepts that pertain to both series circuits and parallel circuits. Since both types of connections are used in combination circuits, the concepts associated with both types of circuits apply to the respective parts of the circuit. The main concepts associated with series and parallel circuits are organized in the table below. Series Circuits The current is the same in every resistor; this current is equal to that in the battery. The sum of the voltage drops across the individual resistors is equal to the voltage rating of the battery. Parallel Circuits The voltage drop is the same across each parallel branch. The sum of the current in each individual branch is equal to the current outside the branches. Each of the above concepts has a mathematical expression. Analysis of Combination Circuits The 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 the number of branches. If the two or more resistors found in the parallel branches do not have equal resistance, then the above formula must be used. An example of this method was presented in a previous section of Lesson 4. By applying one's understanding of the equivalent resistance of parallel branches to a combination circuit, the combination circuit can be transformed into a series circuit. Then an understanding of the equivalent resistance of a series circuit can be used to determine the total resistance of the circuit. Consider the following diagrams below. Diagram A represents a combination circuit with resistors R2 and R3 placed in parallel branches. This is shown in Diagram B. Once the total resistance of the circuit is determined, the analysis continues using Ohm's law and voltage and resistance values to determine current values at various locations. The entire method is illustrated below with two examples. Example 1: The first example is the easiest case - the resistors placed in parallel have the same resistance. The goal of the analysis is to determine the current in and the voltage drop across each resistor. As discussed above, the first step is to simplify the circuit by replacing the two parallel resistors with a single resistor that has an equivalent resistance. In doing so, the total resistance and the total voltage or battery voltage will have to be used. Yet, resistors R1 and R4 are in series and the current in series-connected resistors is everywhere the same.

When all the devices in a circuit are connected by parallel connections, then the circuit is referred to as a parallel circuit. Once transformed into a series circuit, the analysis can be conducted in the usual manner. Parallel Circuits The voltage drop is the same across each parallel branch. As discussed above, the first step is to simplify the circuit by replacing the two parallel resistors with a single resistor that has an equivalent resistance. To determine the voltage drop across the parallel branches, the voltage drop across the two series-connected resistors R1 and R4 must first be determined. If resistor R4 fails shorted. The hole spacings on solderless breadboards are small enough that it is surprisingly easy to mis-locate a component in the manner shown.
