To find equivalent resistance when you have both parallel and series resistors, start simple and expand...
Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit.
For resistors in series: RTOTAL = R1 + R2
For resistors in parallel: RTOTAL = R1R2/(R1+R2)
You can connect 4 resistors in series-parallel, i.e. two in series, both in parallel with another two, and the effective resistance would be the same as one resistor. Similarly, you can connect nine resistors in 3x3 series-parallel, or 16 resistors in 4x4 series-parallel, etc. to get the same resistance of one resistor.
In a parallel circuit, the equivalent resistance is always less than the resistance of the individual resistors. This occurs because the total current can split across multiple paths, reducing the overall resistance. As more resistors are added in parallel, the equivalent resistance continues to decrease. This behavior contrasts with series circuits, where the equivalent resistance is the sum of all resistors and is always greater than any individual resistor.
Three resistors in series have a higher total resistance than three resistors in parallel. In a series configuration, the total resistance is simply the sum of the individual resistances (R_total = R1 + R2 + R3). In contrast, for resistors in parallel, the total resistance is less than the smallest individual resistor and is calculated using the formula 1/R_total = 1/R1 + 1/R2 + 1/R3. Therefore, series resistors result in greater resistance compared to parallel resistors.
In brief, the overall or net resistance changes and the resistors in series and/or parallel can be represented by a single equivalent resistor. If you consider series resistors the equivalent resistance of the series would be: R = R1+R2+ ... +Rx The equivalent resistance of parallel resistors would be: 1/R = 1/R1 + 1/R2 + ... + 1/Rx One rule to always remember when dealing with series and parallel resistors is the voltage across each resistor in parallel will be the same as defined in Kirchhoff Voltage Law and the current across each resistor in series will be the same by Kirchhoff Current Law.

A resistance 'network' consists of a number of resistors connected together in series, or in parallel, or in series-parallel, or as a complex circuit. A 'complex' circuit is one that is not series, parallel, or series-parallel.
The equivalent resistance of resistors connected in series is simply the sum of their individual resistances. Therefore, the equivalent resistance of three 8.0-W resistors connected in series is 24.0 W.
The ratio of the equivalent resistance of series combination to the parallel combination of n equal resistors is (n^2 - 1)/n.
Two eight-ohm resistors in series would have a total resistance of 16 ohms. Two eight-ohm resistors in parallel would have a total resistance of four ohms.
When resistors are connected in series, the total resistance is the sum of the individual resistances. When resistors are connected in parallel, the total resistance is less than the smallest individual resistance.
You can achieve a 30 ohm equivalent resistance by connecting the resistors in a combination of series and parallel. Connect two resistors in series to get 40 ohms, then connect the third resistor in parallel with this combination to achieve a total resistance of 30 ohms.
If three equal resistors are connected in parallel, the equivalent resistance will be one-third of the resistance in series. This lower resistance will result in a higher current flowing through the resistors when connected in parallel compared to when they are in series. Therefore, the power dissipated by the resistors in parallel will be greater than 10W.
You can connect 4 resistors in series-parallel, i.e. two in series, both in parallel with another two, and the effective resistance would be the same as one resistor. Similarly, you can connect nine resistors in 3x3 series-parallel, or 16 resistors in 4x4 series-parallel, etc. to get the same resistance of one resistor.
In a parallel circuit, the equivalent resistance is always less than the resistance of the individual resistors. This occurs because the total current can split across multiple paths, reducing the overall resistance. As more resistors are added in parallel, the equivalent resistance continues to decrease. This behavior contrasts with series circuits, where the equivalent resistance is the sum of all resistors and is always greater than any individual resistor.
Resistors connected in parallel have the same voltage across them, while resistors connected in series have the same current passing through them. In a parallel configuration, the total resistance decreases as more resistors are added, while in a series configuration, the total resistance increases.
Three resistors in series have a higher total resistance than three resistors in parallel. In a series configuration, the total resistance is simply the sum of the individual resistances (R_total = R1 + R2 + R3). In contrast, for resistors in parallel, the total resistance is less than the smallest individual resistor and is calculated using the formula 1/R_total = 1/R1 + 1/R2 + 1/R3. Therefore, series resistors result in greater resistance compared to parallel resistors.
When resistors are wired in series, their resistances are added to find the total resistance. If they are run in parallel, or series-parallel, the formula is different
