Why should always be power factor less than 1?
Power factor can also be equal to 1. Power is greatest when voltage and current are in phase; the "power factor" is used to specify how much less the power is, compared to the product of voltage x current, if they are not.
How do you differentiate the meaning of less and less than?
They are the same - except that in "less", something has a value which is less than some implied value - often the current value. For example, "Please can you make less noise?" implies "Please can you make less noise than you are making now?"
What is the number that is five less than 448 394?
The number that is 5 digits less than your current value is: 448,389.
Which is greater 1kw equals equals KVA?
In the case of DC, and in AC when current and voltage are in phase, a volt-ampere is the same as a watt (and therefore, a kilo-volt-ampere is the same as a kW). In the case of AC, when current and voltage are NOT in phase, power = voltage x current x power factor; the power factor is the cosine of the angle between current and voltage, and it is always less than or equal to one. In such a case, a kVA would be less than a kW.
What is the difference between present value interest factors versus future value interest factor?
The Present Value Interest Factor PVIF is used to find the present value of future payments, by discounting them at some specific rate. It decreases the amount. It is always less than oneBut, the Future Value Interest Factor FVIF is used to find the future value of present amounts. It increases the present amount. It is always greater than one.
The common-emitter forward amplification factor βdc is given by?
A: BETA in an empirical number that for some device varies from 100 to less then 10 it all depends on the current requirement.
Why Voltage x Current do not equal rated power?
In an AC system power is equal to Voltage x Current x Power factor. Power factor is not constant and depends on the type of the load. Ideal value of the Power factor is 1, where as practically remains less then 1.
Does the current reach its maximum peak value at the same instant time in as does the voltage?
Yes if the power factor is unity.Additional AnswerOnly if the load is purely resistive. For a resistive-inductive (R-L) load, the current will reach its maximum value after the voltage reaches its maximum value, and we say the current is 'lagging the voltage'. For a resistive-capacitive (R-C) load, the current will reach its maximum value before the voltage reaches its maximum value, and we say the current is 'leading the voltage'.The angle of lag or lead is called the circuit's 'phase angle' and the cosine of that angle is termed the circuit's 'power factor'. So, for a purely-resistive circuit, the phase angle is zero and the power factor is 1 ('unit'). For R-L circuits, the power factor is less than 1, and is described as 'lagging'. For R-C circuits, the power factor is also less than 1, and is described as 'leading'.

How do you calculate power factor kvr?
Power Factor = KVA/KW. This has no unit. Its value is always 1 or less.

How many watts is 10kva?
Watts is equal to volts x current x Power Factor. The maximum value of Power Factor is 1 for a resistive load. For motors and other inductive devices the Power Factor is less than 1. Your maximum wattage is 10,000 watts and decreases as Power Factor decreases.
What are the characteristics of a CB amplifier?
it is a mode of amplifier connection where the base part of the transistor is made common to both input and output.the circuit diagram is as shown below. the transiator gain(represented by the greek letter beta-B) is usually evaluated by the formula B=output current divided by input current. as we know that when the transistor is connected in common base mode the input pert will be emitter and the output part will be collector and we know that the collector current is quiet less than emitter current. as per the formula gain will be less than one. practically we consider emitter current as equal to collector current and hence B approaches 1 in case of common base mode amplifiers.as the gain is very less it is very less used as amplifiers. generally they use common emitter mode for amplification as this mode optimum amount of amplification.
Why is the class A current less than the peak current?
Not sure what you mean by Class A current. Normally, when measuring AC voltage or current you either measure the peak to peak value or the Root Mean Squared (RMS) value. Since RMS is essentially an average measured over time, it would always be less than Peak to Peak value.
Why a rotor of an alternator at rated power dissipates more heat at a low power factor load than at a high power factor load?
at lower power factor current drawn by load is high and at higher pf the current drawn is less...
How do you convert an RMS current value to a DC value?
RMS current is converted to DC current by using a rectifier. Capacitors and other components are used to make a cleaner DC output with less ripple.
What is the number that is five less than 448 394?
The number that is 5 digits less than your current value is: 448,389.
