## What is the maximum resistance which can be made using?

Hence, the maximum resistance which can be made using five resistors each of 1/5 ohm is 1 ohm..

## 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 between A and B?

therefore the effective resistance between A and B is 10Ω

## What is the effective resistance of a circuit?

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 effective resistance and equivalent 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. … Equivalent resistance is defined to a set of resistors or components having resistance only.

## 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 equivalent resistance?

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

When resistors are connected in parallel, more current flows from the source than would flow for any of them individually, so the total resistance is lower. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current amongst them.

## How do you find the minimum and maximum resistance?

First find the “nominal resistance,” or 470K in this case. Take the nominal value and multiply it by 1 + your tolerance, which is (1+0.1). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1). The highest possible value is 517 K.

## What is the minimum resistance which can be made?

Hence, the minimum resistance which can be made using five resistors each of 1/5 ohms is 1/25 ohms.

## What is the maximum resistance which can be made using four resistors?

2 OhmsMaximum resistance achievable by using the 4 resistors is 2 Ohms.
