## How do you find the equivalent resistance in a series and parallel circuit?

(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 equivalent resistance in a parallel circuit?**

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. That is equal to R/2 and for three equal resistors in parallel, R/3, etc.

**What is equivalent resistance in a series circuit?**

In a series circuit, the equivalent resistance is the algebraic sum of the resistances. The current through the circuit can be found from Ohm’s law and is equal to the voltage divided by the equivalent resistance.

### What is equivalent resistance of the circuit?

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.

**How do you find equivalent resistance in parallel example?**

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.

**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 a combination series parallel circuit?

A combination circuit is one that has a “combination” of series and parallel paths for the electricity to flow. Its properties are a combination of the two. In this example, the parallel section of the circuit is like a sub-circuit and actually is part of an over-all series circuit.

**When 60 resistances each of 60 ohms are connected in parallel their equivalent resistance will be?**

Hence, the equivalent resistance is 36 ohms.

**What is a equivalent resistance?**

In a series circuit, the equivalent resistance is the algebraic sum of the resistances. The current through the circuit can be found from Ohm’s law and is equal to the voltage divided by the equivalent resistance. The potential drop across each resistor can be found using Ohm’s law.

### How do you calculate the resistance of a parallel circuit?

Break down your circuit into series sections and parallel sections.

**How do you calculate equivalent resistance?**

How do you calculate two resistors in parallel? Take their reciprocal values, add the two together and take the reciprocal again. For example, if one resistor is 2 Ω and the other is 4 Ω, then the calculation to find the equivalent resistance is 1 / (1/2 + 1/4) = 1 / (3/4) = 4/3 = 1.33 .

**How to calculate equivalent resistance?**

– The current is the same in every resistor; this current is equal to that in the battery. – The sum of the voltage drops across the individual resistors is equal to the voltage rating of the battery. – The overall resistance of the collection of resistors is equal to the sum of the individual resistance values,

## How do you calculate the total resistance of a parallel?

– The total resistance of two parallel resistors of equal value is 1/2 the value of a single resistor. – The total resistance of three parallel resistors of equal value is 1/3 the value of a single resistor. – ETC.
