## What is the resistance between A and B in the following circuit?

In fig(viii), the resistors between arm FC are in parallel, hence the equivalent resistance between A and B is 2+22×2=1Ω.

## What is effective resistance between A and B?

therefore the effective resistance between A and B is 10Ω

## Does effective resistance include internal resistance?

So then, yes, total resistance includes internal resistance. If the power comes from a battery, current flowing thru internal resistance in the battery therefore decreases the voltage at the battery’s terminals. So then, yes, total resistance includes internal resistance.

## What is the equivalent resistance of the 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. The potential drop across each resistor can be found using Ohm’s law.

## What happens to the effective resistance when two or more resistors are connected in parallel?

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 the effective resistance of your ammeter?

Just like voltmeters, ammeters tend to influence the amount of current in the circuits they’re connected to. However, unlike the ideal voltmeter, the ideal ammeter has zero internal resistance, so as to drop as little voltage as possible as current flows through it.

## What is effective resistance class 10?

Answer: However, if you had a huge and complicated circuit with many resistors, then the effective resistance is the total resistance of the circuit. Effective resistance is usually measured between 2 points. In the figure above, the effective resistance is generally defined as the total resistance across the battery.

## How do I calculate 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.

## What is the difference between resistance and effective resistance?

What is the difference between Equivalent Resistance and Effective Resistance? Equivalent resistance is a purely resistive property, which does not change with any other variable. Effective resistance is another name given to the impedance.

## What is minimum effective resistance?

Minimum effective resistance will be when all the resistors are in parallel combination. So, Reffmin=R/n.

## How do you find equivalent resistance?

The equivalent resistance of a 4 Ω and 6 Ω resistor placed in parallel can be determined using the usual formula for equivalent resistance of parallel branches: 1 / Req = 1 / R1 + 1 / R2 + 1 / R3 … Now the Ohm’s law equation (ΔV = I • R) can be used to determine the total current in the circuit.

## Which is more efficient series or parallel?

Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit. Another advantage to the parallel circuit is that if one loop is disconnected, then the other remains powered.

## What is the formula of effective resistance?

For a circuit with resistances R1 and R2 in series or in parallel as in Figure 2, the effective resistance can be calculated by using the following rules. Rab = R1 + R2. Proof. Let Iab be the current from a to b.

## What is the effective resistance of this circuit?

Effective resistance is usually measured between 2 points. In the figure above, the effective resistance is generally defined as the total resistance across the battery. It is ( = . What this means physically is that the above circuit is equivalent to a circuit with a 9 volt battery in series with a 9k resistor.
