 ## What is the function of a load?

An electrical load is an electrical component or portion of a circuit that consumes (active) electric power.

This is opposed to a power source, such as a battery or generator, which produces power.

In electric power circuits examples of loads are appliances and lights..

Load is the amount of electricity on the grid at any given time, as it makes its journey from the power source to all the homes, businesses and industries within a utility’s territory.

## What is the mean of load?

1a : the quantity that can be carried at one time by a specified means especially : a measured quantity of a commodity fixed for each type of carrier —often used in combination a boatload of tourists. b : whatever is put on a person or pack animal to be carried : pack donkeys with heavy loads.

## What is source and load?

The source is a voltage or current source, and the load is a resistor. … The source is a sensor and the load is an amplifier. The source is signal (waveform) generator that produces various waveforms (sinusoids, saw tooth, square wave, etc.), and the load is an oscilloscope to display such waveforms.

## What is the function of load resistance?

A load resistor is a resistor that has the sole function of increasing the load resistance of the circuit to a specific level. So that’s the “what.” To understand the “what for,” let’s look at two ways load resistance can be critical to proper operation of a DC control or communication circuit.

## 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.

## For what value of load resistance the load current is maximum?

In our Thevenin equivalent circuit above, the maximum power transfer theorem states that “the maximum amount of power will be dissipated in the load resistance if it is equal in value to the Thevenin or Norton source resistance of the network supplying the power“.

A tire’s maximum load is the most weight the tire is designed to carry. Since a tire’s load carrying capacity is related to the tire’s size and how much inflation pressure is actually used, maximum loads are rated with the tire inflated to an industry assigned inflation pressure.

## What is load resistance in circuits?

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 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.

## How do you find the minimum load resistance?

Using Ohm’s Law: V = IR, you can calculate the minimum load if you know the voltage and minimum current ratings. Manipulating this formula yields a resistive load of R = V/I. From here, just plug in the values for V and I, and that is your minimum load resistive value.

## What is the difference between resistance and load?

Resistance is just an proportionality constant (ohm’s law) it is the electrical inertia of a ckt. the resistance of your circuit is defined by the resistor you have placed and internal resistances of your components. where as load resistance is which draws the power from the circuit.
