What is meant by 'wattless power'?
Since reactive power transfers no net energy to the load, it is sometimes called "wattless" power.
What is meant by 1.55 in busbar current calculation?
Busbar current rating for 1 square inch is 1000a.
What is meant by current chopping?
When low inductive currents, such as magnetiing current of transformer, shunt reactors are interrupted by breaker, there is rapid deionization of contact space and may cause the current to be interrupted before its neutral zero. This phenomena is callad current chopping
If pressure is constant and current increases the resistance?
I assume you meant pressure to voltage. The resistance of a conductor is directly proportional to the temperature of the conductor. If the temperature of the conductor increases due to increased current, then the resistance tend to increase too.
What is meant by lagging and leading circuit?
The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage. They describe whether the load current waveform is leading or lagging the supply voltage -always the current, never the voltage. Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.
What is the wattless current?
wattless current means that current by which no power is dissipated (Power=0).
What is meant by 'wattless power'?
Since reactive power transfers no net energy to the load, it is sometimes called "wattless" power.
What is Wattles current?
if the phase angle between e.m.f and current. then the component of Isin is called wattless current
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 meant by the term resistance?
What is meant by the term resistivity?
What is meant by the term fusing current?
Fusing current for a wire is the current at which the wire will act like a fuse (melt).
What is meant by 1.55 in busbar current calculation?
Busbar current rating for 1 square inch is 1000a.
What is meant by expenses payable?
Expense payable is a current liability.
What is meant by a current account deficit on balance of payment?
it is down
What is meant by drift current in diode?
when ever the external voltage is given the movement of charge carriers produce a current i.e drift current
