A load is anything that draws current from a source of potential difference. A 'heavy' load will draw a larger current than a 'light' load. A resistor can certainly be used as a load. A low resistance will draw a larger current than a higher resistance and, so, a low resistance represents a high load while a high resistance represents a low load.

∙ 13y agoOhm's Law:
Voltage = Current x Resistance
Current = Voltage / Resistance
Resistance = Voltage / Current
Ohm's Law can be used to tell you what the resistance of a circuit is if you happen to know what the voltage across the circuit, and the current through the circuit, happens to be. However, it must be remembered that resistance is notaffected by either voltage or by current. Resistance is only affected by the length, cross-sectional area, and resistivity of the conductor. As resistivity is affected by temperature then a change in temperature will likely result in a change of resistance. In general, the resistance of pure metal conductors increase with temperature, whereas the resistance of most insulators decrease with resistance. So, in the case of a pure metal conductor, if the current causes its temperature to rise, then its resistance will rise too -although this has absolutely nothing to do with Ohm's Law. A practical example of this effect is an incandescent lamp which has a relatively low 'cold' resistance, but a relatively high 'hot resistance'.

How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
Relation between voltage and RPM?
voltage depend on current and resistance r.p.m depend on no of pole
What will happen when source resistance equals load restiance?
when source resistance and load resistance are equal maximum power is transfered
What is the difference between shunt and series regulator?
Basic voltage regulators are classified as either SERIES or SHUNT, depending on the location or position of the regulating element(s) in relation to the circuit load resistance.
Is load the same as resistance?
Depending on who is asking about, it could be. But strictly speaking, no. When referring to "load", this could be resistance and reactance (Load at a certain power factor).
What is the relation between internal resistance and load resistance when current is constant in the circute?
The total resistance of a circuit is the sum of the supply's internal resistance and its load resistance, because they are in series with each other. This is true regardless of the magnitude of, or the variation in, the current.
What is relation between resistance power and susceptibility?
Both are same
Can you find the relation between Mahatma Gandhi and Passive Resistance?
ghandi's entire ethos was about passive resistance
Who discovered the relation ship between electic current and resistance?
ohm
What is the difference between on and off state resistance?
On Circuit Resistance = Close to the total load Resistance. Off Circuit Resistance = Near Infinitive High Resistance.
How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
What is the relation between hardness and conductivity?
Resistivity R is the inverse of conductivity G, R=1/G.
Is every resistance load resistance?
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
What is the relation between the velocity of a moving body and the resistance?
I suppose that the relation is directly proportional, because the more is the velocity, the more is the power wasted to keep the body moving, thus the resistance will be greater. JW70
What is the resistance between phase and earth?
You measure at a socket, you should measure well less than one ohm resistance between earth and neutral. .my answer: theoritically it is zero
Relation between voltage and RPM?
voltage depend on current and resistance r.p.m depend on no of pole
Why voltage measured at terminals of battery to which load is connected is always lower than open circuit voltage?
Real-world batteries do not have zero internal resistance. When one connects a load (resistance) to a battery, current begins to flow and the open-circuit potential is divided between the battery's internal resistance and the resistance of the load. Thus, one will measure a lower voltage at the battery terminals when a load is connected, compared to no-load conditions.
