Adding more resistors in parallel always decreases the total effective resistance.
So the total effective resistance of an infinite number of them would be zero ohms.
Nice ! To build a superconducting ring, all you need is an infinite number of resistors.
You don't need the liquid helium, and it superconducts at room temperature !

What is the resulting total resistance if two resistors having 5 and 10 ohms resistance are connected in parallel?
3.333 ohmsHow do we calculate the answer?It is calculated from the "Resistors In Parallel Connection Law" which is:1 / RTOTAL = 1 / R1 + 1 / R2In this case:R1 = 5 and R2 = 10So:1 / RTOTAL = 1/5 + 1/10 = 0.2 + 0.1 = 0.3So:RTOTAL = 1 / 0.3 = 3.333======================================For any number of resistors in parallel . . .Total effective resistance = 1/(1/A + 1/B + 1/C + 1/D + . . . . .)(If you're working with resistor combinations, then you're supposed to know this formula.)If there are only two resistors in parallel, and you use the same formula and simplify it,the total effective resistance turns out to be (A)x(B)/(A + B) .(Just say to yourself "the product over the sum" and you'll remember it.)When the two resistors are 5 ohms and 10 ohms, the total effective resistance is:(5)x(10)/(5+10) = 50/15 = 31/3ohms
How parallel resistors work?
Resistors in parallel work just like highway lanes in parallel. -- The more lanes there are, the more traffic they can carry. -- Any number of lanes in parallel are always wider than the widest single lane, and can carry more traffic than the widest single lane can. "wide lane" = low resistance "narrow lane" = "high resistance" "traffic" = "electric current"
Choose true or falseIf all the resistors in a parallel sub-circuit have the same value the total current can be found by multiplying the current by the number of resistors?
False.
Is resistance a vector?
A vector quantity is one that has a magnitude (a number), and a direction. No, resistance is not a vector quantity; it is a scalar quantity (only magnitude).
What quantity varies place to place in a parallel circuit?
In a parallel circuit voltage remains constant but current will vary with the number of branches (resistors). Remember that Current(amps)=V/R.
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
What is the rule for finding the total resistance of a number of resistors connected in series?
If the resistors are in series, then the total resistance is simply the sum of the resistances of each resistor.
What is the relations for the equivalent resistance of a number of resistors connected in series?
Resistance in series is simply the sum of the resistors. RSERIES = SummationI=1,N(RI)
How many 75K resistors must be put in parallel to provide a total resistance of 15K?
5000 For Parallel resistors: Rtotal = R / N Rtotal is total resistance R = Value of resistors N = number of resistors 15 = 75000 / N N = 5000
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 the effect on the total resistance if increase in resistors in series?
That depends ... in a very interesting way ... on whether they are connected in series or in parallel. -- If the resistors are in series, then the total resistance increases when you add another resistor, and it's always greater than the biggest single one. -- If the resistors are in parallel, then the total resistance decreases when you add another resistor, and it's always less than the smallest single one.
How many number system exist?
infinit
How do you find the resistance of a parallel circuit with n identical resistors?
We have n identical resistors, call them R1, R2 etc up to Rn. All have resistance R. Resistance of the whole circuit = 1/(1/R1 + 1/R2 + ... + 1/Rn) = 1/(n*(1/R)) = 1/(n/R) = R/n So it's the resistance of one resistor, divided by the number of resistors.
Carbon resistors are not available in market of each number of resistance why?
carbon resistors of standard values are manufactured because other values can be obtained by series and parallel combination of standard values. Moreover even standard values do not offer exact Resistance's will have tolerance
How many 176 ohm resistors in parallel are required to carry 5A on a 220V line?
1 resistor has 176ohm resistance (in paralel) ---> given current (I) = 5 A Potential difference (V) = 220 V total resistance = V/I = 220/5 = 44 let the number of resistors be x , 176/x = 44 x = 176/44 = 4 therefore the number of resistors is 4. :)
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.
What factors affect current strength in a series circuit?
The number of resistors and their value. The wire and the junction points have resistance also.
