## What is equivalent resistance in a parallel circuit?

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 ….

## How do you find equivalent resistance?

SolutionThe equivalent resistance is the algebraic sum of the resistances (Equation 10.3. … The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance: I=VRS=9V90Ω=0.1A.More items…•

## What is the difference between total resistance and equivalent resistance?

Lesson Summary More resistance means less current is flowing through the circuit. Equivalent resistance is a different way of indicating ‘total’ resistance, which we calculate differently for series and parallel circuits. In a series circuit, the different components are connected in a single, continuous loop.

## What is the effective resistance?

the resistance to an alternating current, expressed as the ratio of the power dissipated to the square of the effective current.

## How do you find the resistance?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

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

“You can find TOTAL RESISTANCE in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 + … ” Before we get into the calculations, remember what we said at the start of this section: “The total resistance of a parallel circuit is NOT equal to the sum of the resistors (like in a series circuit).

## What does equivalent resistance mean?

The equivalent resistance of a network is that single resistor that could replace the entire network in such a way that for a certain applied voltage V you get the same current I as you were getting for a network.

## Why is equivalent resistance less in parallel?

Resistors in parallel In a parallel circuit, the net resistance decreases as more components are added, because there are more paths for the current to pass through. The two resistors have the same potential difference across them. The current through them will be different if they have different resistances.

## How do you find Thevenin equivalent resistance?

Find the Thevenin resistance by removing all power sources in the original circuit (voltage sources shorted and current sources open) and calculating total resistance between the open connection points. Draw the Thevenin equivalent circuit, with the Thevenin voltage source in series with the Thevenin resistance.

## What is the equivalent resistance between A and B?

3ΩHence, the equivalent resistance between A and B is 3Ω.
