What is the meaning of load resistance?, Load Resistance Defined At the most basic level, load resistance is the cumulative resistance of a circuit, as seen by the voltage, current, or power source driving that circuit. This includes the resistance of the wires and the resistance of any devices connected to those wires.
Furthermore, 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.
Finally, Why is it called load resistance?, It’s just a normal resistor. It’s called a load resistor because it is there to add a load to the circuit. An electrical load is an electrical component or portion of a circuit that consumes electric power.
Frequently Asked Question:
What is difference between load and load resistance?
In electronics, a load means drawing a current, just as in mechanics, a load means the torque offered. (In a car, the load is how much torque the car has to apply to move the car.) A load resistance draws in a load current.
What is the work 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 the relationship of load resistance and internal resistance?
| RINTERNAL = | ℰ | – RLOAD |

What is meant by internal resistance?
Internal Resistance is the resistance which is present within the battery that resists the current flow when connected to a circuit. Thus, it causes a voltage drop when current flows through it. It is the resistance provided by the electrolyte and electrodes which is present in a cell.
Is load and resistance the same?
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.
Why are resistors considered loads?
In a circuit, an element which consumes electric power is considered as a load. Resistor also consumes power. So, resistor can be represented instead of load, or, every load is consuming power as the same way as resistor consumes. Example of load in electric circuits are appliances and lights.
Is a load a resistor?
Load can be anything not specifically a resistor. Basically the device that draws or consumes the current from the circuit is considered to be a load. In practical sense resistor is an device which opposed the flow of current which mean when resistance value gos high the current through the circuit will be minimal.
What is meant by load resistance?
Load Resistance Defined At the most basic level, load resistance is the cumulative resistance of a circuit, as seen by the voltage, current, or power source driving that circuit. This includes the resistance of the wires and the resistance of any devices connected to those wires.
What is load resistance and load current?
The resistance connected at output of any circuit is called load resistance. The current consumed by it is called load current. For example if you connect any resistance at secondary of transformer, it will be load resistance. 3.7K views.
What is the work of load resistance in a circuit?
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 work of resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).
What would the resistance of a load be?
The load resistance or, more generally, the load impedance (in AC circuits) is the equivalent resistance/impedance of the device attached to the output of a given circuit or system. For instance, the equivalent input impedance of a loudspeaker is the “load impedance” of the audio amplifier driving the loudspeaker.
Does load resistance include internal 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, … Voltage is a measure of energy, and energy is always conserved.
What’s the difference between load and resistor?
Resistor observes the flow of current and emits in the form of heat. But the load is something which is utilising the current flow through the circuit and working as per the application. Load resistance is still a resistance. ” load is something which is utilising the current flow”.
What is the relationship between resistance and load?
In electrical, we mean that the current increses. So this means, that as the load increases, the load resistance decreases. This is because a smaller resistance allows more current.
What happens when internal resistance is equal to load resistance?
In electrical engineering, the maximum power transfer theorem states that, to obtain maximum external power from a source with a finite internal resistance, the resistance of the load must equal the resistance of the source as viewed from its output terminals.
