What else can I help you with?
Which is better for generator testing resistive or inductive loads?
resistive loads are best for testing ..they dont introduce phase changes you may test ac devices almost the same as dc inductive loads bring in lots of other factors that give confusing results
Is LED resistive or electronic load?
LEDs are considered electronic loads rather than resistive loads. This is because they operate based on semiconductor properties, requiring a specific forward voltage to conduct current effectively. Unlike resistive loads, which have a linear relationship between voltage and current, LEDs exhibit a non-linear current-voltage characteristic. Additionally, LEDs can have varying current requirements based on their design and usage, further emphasizing their classification as electronic loads.
What is the least destructive load to switch?
No load is the least destructive load to a switch.
What is mean by resistive and reactive load?
A 'resistive' load is one which results in a load current that is in phase with the supply voltage. There is no such thing as a 'purely resistive' load, as all practical loads will have some degree of inductance or capacitance, which will result in a very small lagging or leading phase angle. Typical resistive loads are heating elements in water heaters, etc. A 'reactive' load is one which results in a load current that either lags (inductive) or leads (capacitive) the supply voltage. Purely reactive loads will result in a 90-degree lead or lag but, again, there is no such thing as a purely reactive load as all loads will have some degree of resistance. Accordingly, most reactive loads result in load currents which lag or lead the supply voltage by angles up to just short of 90 degrees. A purely-resistive load would result in true power only; a purely-reactive load would result in reactive power only. Resistive-reactive loads would result in apparent power -a combination (vectorial sum) of true and reactive power.
What is the approximative power factor of an incandescent lamp?
Incandescent lamps are nearly pure resistive loads with a power factor of 1
What is an example of resistive load?
Some examples of resistive loads are: heaters, incandescent lights, fans etc.

Why natural trend to lagging power factor?
Power factor is the cosine of an AC circuit's phase angle, where the expression phase angle is the angle by which a load current lags or leads the supply voltage.Lagging phase angles and power factors occur in resistive-inductive circuits. Leading phase angles and power factors occur in resistive-capacitive circuits.Most industrial and commercial loads are combinations of heating (resistive) loads and motor (inductive) loads -in other words, resistive-inductive loads. Accordingly, lagging power factors tend to be more common than leading power factors.

How do you calculate the amperage given the watts and voltage?
Amps = Watts / (Volts x Power Factor). The Power Factor is one for resistive loads and decreases for inductive loads like motors.
What is the approximative power factor of an incandescent lamp?
Incandescent lamps are nearly pure resistive loads with a power factor of 1
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.
Which home appliances have a resistive load and which home appliances have an inductive load?
water heaters electric stoves toasters space heaters incandescent lights are resistive loads a/c and fans iceboxs and anything with a motor is inductive Type your answer here...
Fan is inductive load or resistive load?
A fan is typically considered an inductive load due to the presence of the motor within it. Inductive loads, such as motors, create magnetic fields when current flows through them, which can cause a phase shift between voltage and current. This phase shift results in a lagging power factor, which is a characteristic of inductive loads. Resistive loads, on the other hand, have a power factor of 1 and do not cause phase shifts.
What is ac1 and ac3 contactor?
AC-1This applies to all AC devices (Resistive loads) with a power factor of at least power factor of 0.95 AC-3This applies to AC Inductive loads. Like squirrel cage motors.
