What are the relation between individual voltages and the total voltage when the resistors are connected in parallel circuit?

total resistance of a parallel connection network of resisters is equals the total resistance divided by one. 1/total R = 1/R1+1/R2+1/R3+................+1/RN since we get 1/total R from the above formula, to get total resistance (total R) just reciprocate the answer. secondly, if u have only two resistors connected in parallel say R1 & R2, then total Resistance total R=(R1*R2 )/R1+R2 inform.mayaprasad@gmail.com


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.


Is the power dissipated in a parallel circuit larger than the power dissipated in a serial circuit?

Consider t resistors with same Ohmic values. If they are in series total resistance Rt = R1 + R2. if they are in parallel then total resistance Rt = 1/R1 + 1/R2. Series connection will have higher resistance.


Two heating elements of 70 ohms and 30 ohms are connected in parallel The total resistance of this circuit would be?

To solve for resistors in parallel take the inverse of the sum of the inverses of all the resistors: 1/((1/r1) + (1/r2) + (1/r3)...)[Google this. It is a lot easier to understand when the proper notation can be drawn.] SO: Rt = 1/((1/70) + (1/30)) = 21ohms


There are three sources of resistence in a parallel circuit two of them are rated at 20 ohms the other 10 ohms what is the circuits total resistance?

The total resistance is 5 ohms. Scroll down to related links and look at "Parallel Resistance Calculator".

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.


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)


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.


You are just asking that let us assume you have connected 2 or 3 resistors in a circuit and the current flowing through the circuit and from all the resistors will be same but how?

If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance


What will happen to the other resistor if the number of resistor decreases?

the voltage across that resistor will increase if it is in series with the other resistors. the current through that resistor will increase if it is in parallel with the other resistors.


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 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.


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 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).


How do you find resistance in a parallel circuit?

resistance inparallel decrease in value proportionally two resistance can be calculated as R1XR2/SUM OF R1+R2. many values can be calculated as a fraction 1/r+1/r2+1/3 ....and take the total sum reciprocal


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.
