According to Ohm’s formula V = IR. respectively then. So, the equivalent resistance or the total resistance of the circuit can be defined as a single value of resistance that can replace any number of resistors connected in series without altering the value of the current or the voltage of the circuit.
Also How do you derive parallel resistance?
derivation of parallel resistance
- replacing I1+I2+I3 by I.
- I=V(1/R1+1/R2+1/R3)
- I/V= 1/R1+1/R2+1/R3.
Subsequently, What do you mean by equivalent resistance? The equivalent resistance represents the total effect of all resistors connected in the circuit, be it series or in parallel. The equivalent resistance can be measured in either a series or parallel circuit, so the total effect of resistors can also be ascertained by finding the equivalent resistance.
How do you find equivalent resistance in parallel and series? Calculate the equivalent resistance of resistors connected in series. Calculate the equivalent resistance of resistors connected in parallel.

How do you find the equivalent resistance in series and parallel?
The equivalent resistance of two resistors connected in series is the sum of the individual resistances. Figure 19: Two resistors connected in parallel. The reciprocal of the equivalent resistance of two resistances connected in parallel is the sum of the reciprocals of the individual resistances.
What is the formula to find equivalent resistance in parallel?
For example, six 100Ω resistors are connected together in a parallel combination. The equivalent resistance will therefore be: RT = R/n = 100/6 = 16.7Ω.
What is parallel combination derive the formula of equivalent resistance?
Resistance in Parallel
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.
What is a parallel resistance?
Resistors are in parallel when one end of all the resistors are connected by a continuous wire of negligible resistance and the other end of all the resistors are also connected to one another through a continuous wire of negligible resistance. The potential drop across each resistor is the same.
What is equivalent resistance class 10th?
The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. … Electrical resistance shows how much energy one needs when you move the charges/current through your devices.
What is the meaning of its equivalent?
1 : equal in force, amount, or value also : equal in area or volume but not superposable a square equivalent to a triangle. 2a : like in signification or import. b : having logical equivalence equivalent statements. 3 : corresponding or virtually identical especially in effect or function.
What is the equivalent resistance of the circuit?
The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined between two terminals or nodes of the network.
What is equivalent resistance between A and B?
So the potentials across all the resistors can be shown as in the figure below. Thus, the equivalent resistance of the given combination of the resistors between A and B is equal to $dfrac{{5R}}{8}$. Hence, the correct answer is option B.
How do you find equivalent resistance in parallel and series?
(d) Using Ohm’s law (V2=I2R2), the power dissipated by the resistor can also be found using P2=I22R2=V22R2. To find the equivalent resistance of the circuit, notice that the parallel connection of R2 and R3 is in series with R1, so the equivalent resistance is Req=R1+(1R2+1R3)−1=1.00Ω+(16.00Ω+113.00Ω)−1=5.10Ω.
What is parallel combination class 10th?
COMBINATION OR A SYSTEM OF RESISTANCES (OR RESISTORS)
In Parallel: When two (or more) resistances are connected between the same two points, they are said to be connected in parallel.
What is parallel combination of resistors calculate the equivalent resistance?
Parallel Circuits
The voltage drop is the same across each parallel branch. The sum of the current in each individual branch is equal to the current outside the branches. The equivalent or overall resistance of the collection of resistors is given by the equation 1/Req = 1/R1 + 1/R2 + 1/R3 …
What do you mean by parallel combination of resistors derive the expression for equivalent resistance for the parallel combination?
Let Rp be the equivalent resistance of the parallel combination of resistors. By applying Ohm’s law to the parallel combination of resistors, we have. I = V/Rp. On applying Ohm’s law to each resistor, we have. I1 = V/R1 ; I2 = V/R2; and I3 + V/R3.
What is parallel resistance class 10?
Resistors in parallel. Resistors in parallel. When two or more resistors are connected in parallel: The current through the circuit is the sum of currents through each branch of the circuit. The potential difference across the two points of the circuit remains the same.
What is the meaning of parallel in science?
: something that is equal or similar. : any one of the imaginary circles on the surface of the Earth that are parallel to the equator and that are shown as lines on maps.
What is the formula of equivalent?
To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)â‚‚. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid’s molar mass by the number of protons.
What is equivalent resistance in A parallel circuit?
Parallel Resistor Equation
If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor.
What is equivalent example?
The definition of equivalent is something that is essentially the same or equal to something else. An example of equivalent is (2+2) and the number 4. Since 2+2= 4, these two things are equivalent. … Equal, as in value, meaning, or force.
What is meaning of equivalent in maths?
The term “equivalent” in math refers to two meanings, numbers, or quantities that are the same. The equivalence of two such quantities shall be denoted by a bar over an equivalent symbol or Equivalent Sign. It also means a logical equivalence between two values or a set of quantities.
What is the meaning of 10 2 or equivalent?
The 10+2 system is a part of the K-12 education system, and equivalent to the International Baccalaureate and GCE Advanced Levels in the west. 10+2 refers to two years of schooling post grade 10 in India since autumn 2002. In India each state has State secondary education boards.
