What is a equivalent resistance?
The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.
What is equivalent resistance in a parallel circuit?
If you have two or more resistors in parallel, look for the one with the smallest resistance. The equivalent resistance will always be between the smallest resistance divided by the number of resistors, and the smallest resistance.
What is equivalent resistance of a circuit?
Equivalent Resistance: The equivalent resistance of a circuit is the total electrical resistance caused by all of the resistors in the circuit acting together against the voltage source. The following two problems demonstrate how to calculate equivalent resistance in a parallel circuit.
How do you find the equivalent resistance?
The equivalent resistance of a number of resistors connected in parallel can be computed using the reciprocal of the resistance i.e. \frac{1} {R}. The reciprocal of the equivalent resistance will be equal to the sum of the reciprocals of each resistance. The unit of resistance is the Ohm i.e. \Omega.
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.
Why is equivalent resistance less in parallel?
So, parallel resistors allow more current. This means that the system as a whole can let more current through, so its resistance is lower.
How do you solve equivalent resistance problems?
Find equivalent resistance of the network. Find current in each resistor. Find voltage drops VAB,VBC,VCD. Medium.
What is the equivalent resistance of two resistors in parallel?
Two identical resistors in parallel have an equivalent resistance half the value of either resistor.
What is the unit for equivalent resistance?
The equivalent resistance of a number of resistors in series is the sum of the individual resistance values. The unit of resistance is the Ohm (Ω), which is equal to a Volt per Ampere (1 Ω = 1 V/A).

How do you find the equivalent resistance of two resistors when connected in parallel?
Ans: The net resistance of the resistors connected in parallel is given as:1 R p = 1 R 1 + 1 R 2.1 R p = 1 3 + 1 6.1 R p = 1 R 1 + 1 R 2 + 1 R 3.1 R p = 1 3 + 1 3 + 1 3 = 3 3 = 1.
How do you find the equivalent resistance between a and B?
Solution : In (Fig. 3.22) (a), total resistance in the path `ACB`, i.e., `R_1 = 8.5 Omega + 3.5 Omega = 12 Omega`
Since `R_1 and R_2` are in parallel, the effective resistance between the points `A and B`, i.e.,
`R = (R_1 R_2)/(R_1 + R_2) = (3 xx 12)/(3 + 12) Omega = 2.4 Omega`
In (Fig.
What is the Equivalent Resistance?
The equivalent resistance is where the total resistance connected either in parallel or in series. Electrical resistance shows that how much energy will be required when we move the charges i.e. current through the circuit. If we need lots of energy, then the resistance necessary should also be high. The equivalent resistance of a network is the single resistor which can replace the entire network in such a way that for a certain applied voltage as V we will get the same current as I.
What does more resistance mean?
More resistance means for the less current flowing through the circuit. If the electrical circuit is having many resistances connected, then we need to find their accumulated resistance value. Thus, the equivalent resistance is a different way of indicating the total resistance. It will be calculated differently for series and parallel circuits.
What is the unit of resistance in electrical circuits?
The equivalent resistance of a number of resistors in series will be the sum of the individual resistances. The unit of resistance is the Ohm i.e. in symbol Omega.
What is equivalent resistance?
What is Meant by the Equivalent Resistance? In Physics, an equivalent Resistance is defined as the sum of the resistance of the resistors connected in a circuit. The resistors can be connected in series or parallel. Assume that R1, R2 and R3 be the three resistors.
