What is meant by wattless current?
Current flowing through an ac circuit in which power consumed is zero is called wattless current.
What is Wattles current?
if the phase angle between e.m.f and current. then the component of Isin is called wattless current
What is meant by 'wattless power'?
Since reactive power transfers no net energy to the load, it is sometimes called "wattless" power.
What do you mean by wattless current and power factor in AC?
Watts = Current x Voltage x Power Factor In an AC circuit both the voltage and current are sine waves. When they are in phase (waveforms lie over top of one another) the PF is one. As they become out of phase the PF decreases to zero. This happens when the phase difference is 180 degrees. In this case the positive peak of current is at the same place in time as the negative peak of voltage or vice versa. So when PF is zero you coul say you are getting zero watts.AnswerAn a.c. load current can be resolved into two components. One, in phase with the supply voltage, and responsible for supplying true power to the load. The other, at right angles to the supply voltage, and responsible for supplying reactive power (e.g. the magnetic field, in the case of a motor). As reactive power is sometimes termed 'wattless power', we can say that the second component of this current is 'wattless current'.
What does watless mean?
The spelling closest to this word is wattless [two t's]. A wattmeter is an instrument for measuring electric energy and if there is none then it would be wattless. Wattles [with one s] are acacia trees indigenous to Australia.
What is wattless capacitive power?
I believe you're referring to reactive power. Reactive power is present any time the voltage and current are AC signals and not in phase. Some current simply charges and discharges the load reactance, and therefore does not deliver real power to the load.
What is VAR?
Volt-Ampere Reactive. It is the reactive component of power when the Power Factor is less than unity (1.0). It is usually measured in KVAR - 1000's of VAR.

How do you get a current ratio?
Formula for current ratio is as follows: Current ratio = Current assets / current liabilities
Can a current stop within day?
What sort of current? River current? Electrical current? Tidal current? large scale ocean current?
Canary Current is it a warm or cold current?
The canary current is a cold current.
What is the equation for current ratio?
Current Ratio = Current Assets / Current Liabilities
