In parallel connection ends of resistance are connected at same point. In parallel connection current through all the resistor are different but voltage across all the resistor remain same since all of them are connected from same point.
Q. When three different resistances R1 R2 and R3 are connected in parallel where R1 R2 R3 the equivalent resistance of the combination will be?
it is clear from the equation that value of R is less than R1 orR2 or R3=1 , therefore equivalent resistance of this combination is less than 1 ohm .

Q. When R1 R2 and R3 are connected in series then what will be resultant resistance R of the combination?
1/R1 + 1/R2 + 1/R3 = 1 / R. Similarly, For n number of resistors connected in parallel, The Total Equivalent resistance = 1/R1 + 1/ R2 +……. + 1/Rn = 1 / R.
Q. What is combination resistance?
Series Combination Resistances are said to be connected in series between two points if they provide only a single path between two points. Resistances are connected in series if same current flows through each resistance when some potential difference is applied across the combination.
Q. What formula would be used to calculate the equivalent resistance if R1 and R2 are connected in parallel?
Rtotal = R1×R2/(R1+R2) Please enter two resistor values, the third value of the parallel circuit will be calculated. You can even enter the total resistance Rtotal and one known resistance R1 or R2.
Q. What is the formula for equivalent resistance when two resistances are connected in parallel?
If the resistors are connected in parallel along with a battery, then the total current I is calculated as a sum of the separate value of current through each branch. It is given as: I = I1+I2+I3+….
Q. What is equivalent resistance obtain the expression for the equivalent resistance when two resistors are in parallel?
When resistors are in parallel, the potential difference (V) across each resistor is the same. A current I entering the combination gets divided into I1, I2, I3 and I4 through R1, R2, R3 and R4 respectively, such that I = I1 + I2 + I3 + I4. where RP is the equivalent or effective resistance of the parallel combination.
Q. What is the ratio of equivalent resistance of series combination?
What is the ratio of equivalent resistance of series combination of n equal resistance to the equivalent resistance in parallel combination of these n resistances ? Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. Thus, RsRp=nrr/n=n2.
Q. How will you connect three resistors Resistance 2 ohm 3 ohm?
Thus, we can obtain a total resistance of 4Ω by connecting parallel combination of 3Ω and 6Ω resistors in series with 2Ω resistor. (b) In order to obtain a total resistance of 1Ω from three resistors of 2Ω, 3Ω and 6Q, all the three resistors should be connected in parallel.
