What is the effect of an inductive or capacitive load under no load conditions?
A load of any type,,,inductive or capacitive , would effect the circuit even if THOSE "loads" had no load on them. They would still have a load effect on the circuit they are connected to.Answer'Under no-load conditions' means that no load is connected to the supply. So your question doesn't make sense!
Should all three phases of 3 phase motor are to be equal on no-load and load conditions?
Ideally all three phase currents will be equal. There may exist some voltage imbalance from the power source, which will result in unequal currents.
How is ammeter and voltmeter attached to a circuit?
Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.
What is floating load?
A load not connected to ground but connected in a feedback circuit is floating load
Is the power transformer switched off under light load conditions?
No, the transformer has to supply the load, whether it is light or heavy.
What is the difference between Load Current Line Current and Phase Current?
A load current is a current drawn by an electrical load. In other words, it is the current flowing from the source to the load.For a single-phase system, a line current is a current flowing through the line, or 'hot', conductor, while the current through the neutral conductor is called the neutral current.For a three-phase system, the three 'hot' conductors between the load and the source are called 'lines' and, so, the currents passing through them are called 'line currents'. For a three-phase system, loads are either connected between line conductors (delta-connected system) or between each line and the neutral (star- or wye-connected system), and represent the phases -so the currents passing through the loads are called 'phase currents'.For a balanced three-phase system, the line current is 1.732 times the value of a phase current, where the phases (loads) are connected in delta. For phases (loads) connected in star (or 'wye') the line current is numerically-equal to the phase currents.
When a two winding transformer is connected as an autotransformer its efficiency under full load is?
remain same
Why SCRs are connected in parallel?
When the load current exceeds the SCR current rating, SCRs are connected in parallel to share the load current. Further the holding currents of the devices should not be so much different that at reduced load current one of the device gets turned-off because of fall of current through it blow its holding current value.
How many connecting load in 240 volt 50Hz?
One can not determine the total load that can be connected only stating voltage and frequency. One must sum up the KW load of all the devices to be connected, which gives the total connected load. Then the power source system to be designed to cater to the that connected load.
What does no load condition refer to?
If transformer then it refers to that, the primary is charged, but secondary is open, (no load is connected) If motor, it refers to that no load is connected to motor, the shaft is decoupled from the load, but running with out any load.
Is every resistance load resistance?
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
Why voltage measured at terminals of battery to which load is connected is always lower than open circuit voltage?
Real-world batteries do not have zero internal resistance. When one connects a load (resistance) to a battery, current begins to flow and the open-circuit potential is divided between the battery's internal resistance and the resistance of the load. Thus, one will measure a lower voltage at the battery terminals when a load is connected, compared to no-load conditions.
