But what if we want to connect various resistors together in "BOTH" parallel and series combinations within the same circuit to produce more complex resistive networks, how do we calculate the combined or total circuit resistance, currents and voltages for these resistive 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 voltage across them.

For example, in the following circuit calculate the total current I taken from the 12v supply. T At rst glance this may seem a dif cult task, but if we look a little closer we can see that the two resistors, R and R are actually both connected together in a "SERIES" combination so we can add them together to produce an equivalent resistance the same as we did in the series resistor tutorial. Using our resistors in parallel equation we can reduce this parallel combination to a single equivalent resistor value of R using the formula for two parallel connected resistors as follows.

Now by using , the value of the circuit current I is simply calculated as:So any complicated resistive circuit consisting of several resistors can be reduced to a simple single circuit with only one equivalent resistor by replacing all the resistors connected together in series or in parallel using the steps above. It is sometimes easier with complex resistor combinations and resistive networks to sketch or redraw the new circuit after these changes have been made, as this helps as a visual aid to the maths.

Then continue to replace any series or parallel combinations until one equivalent resistance, R is found. Lets try another more complex resistor combination circuit. Resistors in Series and Parallel Example No2Find the equivalent resistance, R for the following resistor combination circuit.

Starting from the right hand side and using the simpli ed equation for two parallel resistors, we can nd the equivalent resistance of the R to R combination and call it R.

When solving any combinational resistor circuit that is made up of resistors in series and parallel branches, the rst step we need to take is to identify the simple series and parallel resistor branches and replace them with equivalent resistors. This step will allow us to reduce the complexity of the circuit and help us transform a complex combinational resistive circuit into a single equivalent resistance remembering that series circuits are voltage dividers and parallel circuits are current dividers.

However, calculations of more complex and resistive bridge networks which cannot be reduced to a simple parallel or series circuit using equivalent resistances require a different approach.

These more complex circuits need to be solved using , and which will be dealt with in another tutorial. In the next tutorial about Resistors, we will look at the electrical potential difference voltage across two points including a resistor. Related Papers. By Shomi Ahmed.

Resistors in Series and Parallel

The total resistance in the circuit with resistors connected in series is equal to the sum of the individual resistances. Most circuits have more than one component, called a resistor, that limits the flow of charge in the circuit. A measure of this limit on charge flow is called resistance. The simplest combinations of resistors are the series and parallel connections. The total resistance of a combination of resistors depends on both their individual values and how they are connected. Resistors are in series whenever the flow of charge, or the current, must flow through components sequentially. Resistors in Series : These four resistors are connected in series because if a current was applied at one end, it would flow through each resistor sequentially to the end.

Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. The equivalent resistance of a combination of resistors depends on both their individual values and how they are connected.

The amount of current in a series circuit is the same through any component in the circuit. This is because there is only one path for current flow in a series circuit. Because electric charge flows through conductors like marbles in a tube, the rate of flow marble speed at any point in the circuit tube at any specific point in time must be equal.

Analysis Techniques for Series Parallel Resistor Circuits

The goal of series-parallel resistor circuit analysis is to be able to determine all voltage drops, currents, and power dissipations in a circuit. The general strategy to accomplish this goal is as follows:. This may sound like an intimidating process, but its much easier understood through example than through description.
