When many resistances are connected in series, the equivalent resistance is

greater than the greatest single resistance.

When many resistances are connected in parallel, the equivalent resistance is

less than the smallest single resistance.

When resistors are connected in series, their combined effective resistance is equal to the sum of

their individual resistances ... greater than either individual resistance.

When resistors are connected in parallel, their combined effective resistance is equal to the reciprocal

of the sum of the reciprocals of their individual resistances ... less than either individual resistance.

You would connect them in series. The equivalent resistance would then be the sum of the individual resistances.

RSeries = SummationI=1toN (RI)

How can you connect resistors to produce an equivalent resistance which is the same as the resistance of each individual resistor?

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.


How do you connect several resistances if you want to decrease in total resistance without reducing the number of resistors?

The resistors should be connected in parallel .


How can you get 25ohm total resistance from 100 resistors having 1 ohm resistance?

Connect 50 of them in series. This would have 50 ohm as equivalent. Same way have another 50 pieces in series. This again would have 50 ohm as effective value. Now connect these in parallel to each other. Now the effective would become as 25 ohm.


Characteristics of resistor in series and parallel connection?

Resistors in series add resistance to an electrical circuit. For instance two 1 ohm resistors in series will have 2 ohms of resistance. Resistors in parallel divide the resistance between them. Thus two 2 ohm resistors in parallel will have 1 ohms total resistance. resistors of different sizes work the same way. a 4 ohm and 2 ohm resistor in series have 6 ohms resistance. While in parallel they will have .75 ohm resistance. resistance formulas: series: Req = r1+r2+r3....+rx parallel: Req = 1/r1 + 1/r2 + 1/r3 ..... +1/rx


How do you place 3 resistance to get the total resistance of 1 ohm?

It depends on the resistance of each resistor. If each resistor, for example, is 0.333 ohm, then you could connect them in series. If each resistor, for example, is 3 ohms, then you could connect them in parallel.

If a 1 ohm resistor is parallel with a 100 ohm resister what's the total resistance?

If two 1-ohm resistors are connected in parallel, their resistance is 0.5 ohms. If they are connected in series, their resistance is 2 ohms. It is not possible to connect only two resistors in series parallel.

Is it possible to connect a group of resistors of value R in such a way that the equivalent resistance is less than R?

Yes. When resistors are connected in "parallel" (all the left ends connected together and all the right ends connected together) the effective resistance is always less then the smallest resistor in the group. For example If you connected a 2 ohm in parallel with a 4 ohm the effective resistance is 1.33 ohm. To your question; if you connect N equal resistors R in parallel the effective resistance would be R/N . The formula for calculating effective resistance R of a group R1, R2, R3, ... in parallel is: 1/R = 1/R1 + 1/R2 + 1/R3 + .... Note; write the right side as a single fraction by getting a common denomenator then invert to get R.


Can two electric resistors connect in both series and parallel?

yes two resistors can connect both in series and parallel because when you connect two resistors in a closed loop, the same intensity of current flows across them and also they are connected to the same nodes which are the conditions for series and parallel connections respectively.
