∙ 14y agoResistive load is real load, requiring real power. capacitive load is reactive load requiring reactive power. In a DC circuit, a resistive load will use the same amount of power constantly while a capacitive load will use a large amount initially that will decay to almost zero fairly quickly as the capacitor becomes charged to the source voltage level.

In a purely resistive ac circuit the current and voltage?
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.
Does low load in transformer lead to low power factor?
Power factor is determined by the nature (resistive, inductive, capacitive) of a load, not whether it is a low load or a high load.
Is computer is Resistive load?
It is resistive much load
What is the value of power factor for a pure capacitor?
0. Power factor has to do with the amount of real power. if you have a purely capacitive load, there is no real power flow, thus pf = 0. For purely resistive load, power factor will be 1.0.
What are example of capacitive load?
capacitor bank
What is Pure Resistive?
A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.
In a purely resistive ac circuit the current and voltage?
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.

Is battery is inductive or capacitive load?
A battery is usually thought of as a source, not a load. If you are charging a battery, then it will be resistive, especially if you are attempting to charge it like you should, with a DC power supply (not AC).
What is the difference between an inductive and a capacitive load?
Resistance load it means there is passive load to impede current flow. Inductive load means there is a coil as a load while still a passive it has its own characteristics which differs from a resistive load which is linear while inductive is not linear load
Does low load in transformer lead to low power factor?
Power factor is determined by the nature (resistive, inductive, capacitive) of a load, not whether it is a low load or a high load.
What are capacitive loads?
A load, at low frequencies, can be either capacitive, resistive, or inductive. At high frequencies, all three aspects exist. At low frequencies (say <= 10 MHz), a capacitive load is a capacitor, represented by an ideal cap, the MOScap, or a junction cap. An unintentional capacitive load would be the wire or conductor to another wire or conductor or ground. At high frequencies (say >= 1 GHz), all things have a capacitive nature. The higher the frequency, the worst is the capacitive leak A capacitive load means just that the load acts like a capacitor load as opposed to a inductor or resistive load
When using a resistive load bank to test a generator do you load it to the kW or the kVA?
When using a resistive load bank to test a generator, it does not matter if you load the generator to its kW or kVA rating, because those two numbers are the same when considering a resistive load. Power factor, which is the difference between true and apparent power, only comes into play when there is a reactive (inductive or capacitative) load.
Is computer is Resistive load?
It is resistive much load
Why the load voltage increases when the load used is capacitive?
capacitive reaction
What is the phase angle difference between inductive load and resistive load?
The phase angle is defined as the angle by which the load current leads or lags the supply voltage.For a purely-resistive load, the phase angle is zero, because the load current is in phase with the supply voltage.For a purely-inductive load, the phase angle is 90 degrees lagging.But few loads are either purely-resistive or purely-inductive; typically, most loads are resistive-inductive. This means that, typically, the phase angle lies somewhere between zero and 90 degrees.
What is no load full load?
load in terms of any electrical machine is of 3 types mainly :- 1)resistive load--it means the load connected is a resistor only. 2)inductive load--it means the load applied is an inductor only. 3)capacitive load--it means the load is capacitor only. 4)also there may be combination of all these types or any two of the above loads like capacitive -resistive load;capacitive -inductive load. NO LOAD:--- as it is very clear from the word itself that it is no load that means no load has been applied to the machine..i.e.the output terminal of machine is open circuited FULL LOAD:-- the maximum load value that can be applied to the machine at which it can work without damaging any part of the machine is called machine working at full load ---------mrityunjay pandey (kiit university ,btech 2nd year)
