1/Rtotal = 1/R1 + 1/R2 + 1/R3 1/Rtotal = 1/0.2 + 1/0.4 + 1/0.5 1/Rtotal = 10/2 + 10/4 + 10/5 1/Rtotal = 100/20 + 50/20 + 40/20 1/Rtotal = (100 + 50 + 40) / 20 1/Rtotal = 190 / 20 Rtotal = 20 / 190 = 0.11 ohms Note that in any circuit where a number of resistors is connected in parallel, the total resistance will always be smaller than the smallest resistor of the bunch. That's a quick way to check and see if your work is anywhere in the ball park.
What else can I help you with?
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.
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 .
Total resistance of parallel resistors is always less than the?
The smallest resistor.
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.
What is the difference between connecting resistors in parallel and in series?
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.
Does you add the shorted resistors in finding the total resistance?
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
What are the differences between resistors connected in parallel and resistors connected in series, and how do these configurations affect the overall resistance in a circuit?
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.
How do you draw this you have three 20 ohm resistors available. how would you connect these three resistors to produce a 30 ohm equivalent you must use all three resistors?
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.

What is the relation between the total resistance of a parallel connection network of resistors in reference to their single resistance?
The equivalent total resistance of resistors connected in parallel is lower than the resistance of the smallest resistor. The general formula for calculating the total resistance of n resistors in parallel is Rt = 1 / (1/R1 + 1/R2 + ... 1/Rn) For two resistors in parallel, the formula simplifies to Rt = (R1 x R2) / (R1 + R2) If R1 = 10K ohms and R2 = 4.2K ohms, the total resistance of R1 in parallel with R2 is (10,000 x 4,200) / (10,000 + 4,200) = 2957.7 ohms. The total resistance is less than the smallest resistor (4.2K). For three resistors in parallel, the formula is Rt = 1 / (1/R1 + 1/R2 + 1/R3) If R1 = 100 ohms, R2 = 68 ohms, R3 = 1K ohm, the total resistance of these three resistors connected in parallel is: Rt = 1 / (1/100 + 1/68 + 1/1000) = 38.9 ohms The total resistance (38.9 ohms) is lower than the smallest resistor (68 ohms).
The total resistance of a circuit with three 30 ohm resistors in parallel is ohms?
If the parallel resistors are equal, then the total resistance (in this case, with three resistors) will decrease by a factor of 3. I suggest you verify this with the standard formula for parallel resistance: 1/R = 1/R1 + 1/R2 + 1/R3, replacing the value 30 for R1, R2, and R3, and calculating R, the combined resistance.
Total resistance of parallel resistors is always less than the?

What is the equivalent resistance of a pair of 8 ohm resistors in series circuit?
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.
