## What is the difference between resistance and load?

Resistance is the usual term you have heard about everywhere.

The proportionality constant from ohm’s law.

Load resistance is also a resistance, but it has a very specific meaning in the context of electric circuits; it is the resistance connected between the output stage of a circuit, and the ground..

## What is the difference between Thevenin and Norton Theorem?

What is the difference between Thevenin and Norton theorems? – Norton’s theorem uses a current source, whereas Thevenin’s theorem uses a voltage source. – Thevenin’s theorem uses a resistor in series, while Norton’s theorem uses a resister set in parallel with the source.

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

Internal resistance is the resistance within a battery, or other voltage source, that causes a drop in the source voltage when there is a current. … External resistance or simply called Resistance is generally referred as the opposition to the flow of current offered by any load.

## Is load equal to force?

Force is a measure of the interaction between bodies. … Force is known as a vector quantity, as it has both direction and magnitude. Load. Load is a term frequently used in engineering to mean the force exerted on a surface or body.

## What is load resistance and internal resistance?

“The load resistance in a circuit is the effective resistance of all of the circuit elements excluding the emf source. … The internal resistance of a battery represents the limitation on the efficiency of the chemical reaction that takes place in the battery to supply current to the load.

## What does too much resistance mean?

Resistance measurements are normally taken to indicate the condition of a component or a circuit. The higher the resistance, the lower the current flow. If abnormally high, one possible cause (among many) could be damaged conductors due to burning or corrosion.

## What is minimum load resistance?

The minimum load is usually the highest resistance that draws the least current from the supply. When the minimum load conditions are not met, the power supply may experience some instability such as flickering and shutdowns. The minimum load for resistive load can be calculated if the minimum current is known.

## How do you find Thevenin resistance?

Remember the three step process:Find the Thevenin Resistance by removing all voltage sources and load.Find the Thevenin Voltage by reconnecting the voltage sources.Use the Thevenin Resistance and Voltage to find the total current flowing through the load.

## What is minimum power?

The principle of minimum energy is essentially a restatement of the second law of thermodynamics. … It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at equilibrium.

## How is load regulation percentage calculated?

Load regulation (percent) = 100 x (voltage no load — voltage full load) divided by voltage full load. Line regulation is another measure of voltage regulation.

## How do you find equivalent resistance?

Parallel CircuitsThe 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 …

## Does load resistance include internal resistance?

All materials have some resistance. … When a load resistance is connected, current flows through the cell and a voltage develops across the internal resistance. This voltage is not available to the circuit so it is called the lost volts, . can also be calculated as using Ohm’s Law .

## What is load in machine?

The weight lifted by a machine is called Load. It is denoted by ‘W’. MECHANICAL ADVANTAGE. The ratio of weight (load) lifted by a machine to the force(effort) applied on a machine is called mechanical advantage of the machine.

## What happens when resistance is high?

A high resistance in the circuit means a very low current flowing in it when the voltage of the source is constant. … Low resistance in the circuit means a higher current is flowing in the circuit. It depletes the battery at a faster rate which means the battery can not last for a long time.

## How do you find the resistance of a load?

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 use of load resistance?

The load resistance in a circuit is the effective resistance of all of the circuit elements excluding the emf source. In energy terms, it can be used to determine the energy delivered to the load by electrical transmission and there appearing as internal energy to raise the temperature of the resistor.

## What is considered high resistance in a circuit?

Resistor Symbols Low resistance, for example 1Ω or less implies that the circuit is a good conductor made from materials such as copper, aluminium or carbon while a high resistance, 1MΩ or more implies the circuit is a bad conductor made from insulating materials such as glass, porcelain or plastic.

## What is meant by load regulation?

Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply’s load (such as a change in resistance value connected across the supply output).

## How do you find resistance in parallel?

You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +… If one of the parallel paths is broken, current will continue to flow in all the other paths.

## What happens when load increases?

Originally Answered: what happens when load increases? As load increases the Current increases because, the loads are connected in parallel to supply same voltage so , if loads are connected in parallel the current increases.

## What happens when resistance is too high?

If resistance is too high, current will be low if voltage is okay. NOTE: When the voltage stays the same, such as in an Automotive Circuit… current goes up as resistance goes down, and current goes down as resistance goes up.
