If you need a resistor of a certain value, and you have no resistors with small enough values,
you can create the one you need by connecting several of those you have in parallel.
The effective net resistance of resistors in parallel is always less than the smallest individual.
And the more resistors you add in parallel, the smaller the net effective resistance becomes.

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 .
In a circuit the voltage across all resistores is the same?
It depends upon the connection of the resistors, if the resistors are connected in parallel then the voltage is same where as in case of resistors connected in series the voltage is different across different resistors.
A circuit contains a 10 pF capacitor and a 50 pF capacitor connected in parallel.What is the total capacitance of this circuit?
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
A resistor has a resistance of 176 ohm How many of these resistors should be connected in parallel so that their combination draws a current of 5 amperes from a 220 volt supply line?
4 resistors were connected in parallel it yields 5A of current from 220V supply.
How are resistor connected in series?
when we want maximum resistance they are connected in series. when resistors are connected in series total resistance is maximum when resistors are connected in parallel total resistance is minimum for series total R=R1+R2+R3......... for parallel R1 in parallel to R2 total 1/R=(1/R1)+(1/R2) ie R=(R1*R2)/(R1+R2)
What picture represents two resistors wired in parallel?
It represents that two resistors are connected in parallel.
Two resistors are connected in parallel to a battery What must the votlage across these two resistors?
Both resistors will have the voltage of the battery.

What is the resistance between any two of the corners if Three 3 ohm resistors are connected such that it make triangle.?
2 ohms. It is like connecting two 3 ohm resistors in series and then these two series resistors are connected in parallel with third 3 ohm resistor in parallel
What is the current for two resistors 25 amp and 35 Amp connected in parallel?
"Amp" is not a specification associated with resistors. It could be anything.
When 2 resistors are connected in parallel r1r2 are?
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.

What is the equivalent resistance when resistors are in a cube?
The equivalent resistance, from corner to corner, of 12 resistors connected in a cube is 5/6 that of a single resistor.Proof:Start from one corner and flow current through to the opposite corner. You have three resistors. Each of those three resistors is connected to two resistors, in a crisscross pattern. Those six resistors are then connected to three resistors which are connected to the other corner. By symmetry, the voltages at the upper junctions are the same, and then same can be said for the lower junction. You can then simplify the circuit by shorting out the upper junctions and (separately) the lower junctions. This means the circuit is equivalent to three resistors in parallel, in series with six resistors in parallel, in series with three resistors in parallel. This is 1/3 R plus 1/6 R plus 1/3 R, or 5/6 R.
What is a parilel circuit?
A parallel circuit is one where the elements in question are connected "side-by-side". The term is generally use to contrast against a series circuit where the elements are connected "end-to-end". As an example take two resistors and arbitrarily label the leads "A" and "B". If you connect the two resistors to each other such that A on one is connected to A on the other and B on the one is connected to B on the other, you have created a parallel connection of the two resistors.
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.
