5 ohms...

∙ 14y agoSorry, but I will not give you a specific answer. You need to find the resistance of your particular conductor (in Ohms/cross sectional area-which you already have), multiply that by the number of feet (or meters, as the chart will show) and then divide by 2 as the current will flow through both sections simultaneously. As for the resistors, when there's only 2 in parallel, simply divide by 2. If this is an AC circuit then the resistance (actually now it is impedance VARIES WITH FREQUENCY running through the circuit.

∙ 12y agoThree 15 ohm resistors connected in parallel are equivalent to one 5 ohm
resistor. Across a 30 volt battery, that 5 ohm resistor will pass 6 amperes,
and dissipate 180 watts.
So each of the 3 resistors will conduct 2 amperes of current, and dissipate
60 watts of heat.
That's the Physics and Engineering solution. In practice, 6 amperes of current
out of a battery, and 60 watts dissipation by a resistor, are both a lot to ask,
without a special battery and special resistors.

∙ 14y agoIf three 15-ohm resistors are connected in parallel, then their net effective resistance is 5 ohms.
It makes no difference what they're connected to, or if they're connected to anything, or whether
or not you have any plans to ever connect them to anything.

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 .
What is a resistance network?
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.
How are parallel resistors connected?
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 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 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)
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.

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.

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
How many 40 Ω resistors connected in parallel are required to carry 1.5 A on a 12.0 V line?
The required resistance is 12/1.5 = 8Ω.Five 40Ω resistors in parallel have an effective resistance of 8Ω.

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.
Which is the total resistance of a circuit that contains twenty 100 ohms resistors connected in parallel?
When resistors of the same value are wired in parallel, the total equivalent resistance (ie the value of one resistor that acts identically to the group of parallel resistors) is equal to the value of the resistors divided by the number of resistors. For example, two 10 ohm resistors in parallel give an equivalent resistance of 10/2=5Ohms. Three 60 ohm resistors in parallel give a total equivalent resistance of 60/3 = 20Ohms. In your case, four 200 Ohm resistors in parallel give 200/4 = 50 Ohms total.
