How do you control voltage and power factor for alternator?
Since it the rate at which the flux is cutting the conductor determines the (EMF) electromotive force which is the voltage, the best way to control voltage is to adjust the speed of the engine through the governor, coupled with an automatic voltage regulator.
What is the ratio of rms load voltage to mean load voltage?
The mean load voltage, in other words the average voltage, is zero in an ac system.
Can the amount of energy carried by a power line be increased by raising voltage?
Yes, by increasing the voltage in a power line, the amount of energy carried can be increased. This is because power (P) is the product of voltage (V) and current (I), and increasing the voltage while keeping the current constant will result in higher power carrying capacity. However, it is important to consider the limitations of the equipment and the safety considerations when increasing voltage levels.
What do you understand by regulation in a transformer?
Regulation of transformer means percentage reduction of transformer secondary voltage due to transformer loading as compared to its no load voltage.Another AnswerA transformer's voltage regulation is defined as 'the change in its secondary voltage, from no-load to full-load, at a specified power factor, expressed as a percentage of its full-load voltage, with the primary supply voltage held constant'.
What is the relationship between the potential difference across a battery and the potential difference across each load in a parallel circuit?
Without specifics (are all the batteries end to end or are some loads between batteries, are all the loads the same resistive, capacitive or inductive value...), the generic answer is: the sum of supplied voltages must equal the sum of voltage drops across the loads.
What amount of voltage that is used by each load depends on the?
drop
What happens to the lamp in a series connecting if more loads are added?
The lamps each get more dim with each load added, because in a series circuit, the amount of voltage per load is determined by the total voltage divided by the amount of loads. If one lamp burns out, the rest stop working because with that one burnt lamp, the circuit is broken
What happens to the other lamps in a series connection if more loads are added?
The lamps each get more dim with each load added, because in a series circuit, the amount of voltage per load is determined by the total voltage divided by the amount of loads. If one lamp burns out, the rest stop working because with that one burnt lamp, the circuit is broken
How do you calculate line regulations?
no load voltage - full load voltage by full load voltage
What type of load is LED?
Direct current variable voltage requirements for each application and would be a resistance load.
Where is the load on a string of Christmas lights?
The load on a string of Christmas lights is typically located in the bulb itself. Each bulb is designed to produce light and consumes power when electricity passes through it. The collective load of all the bulbs on the string determines the amount of power required to illuminate the lights.
Why transformer rated kva?
The correct symbol for kilovolt amperes is 'kV.A, not kva. A volt ampere is the product of the transformer's secondary rated voltage and its rated current. It is not rated in watts, because the transformer designer has no idea what sort of load is to be applied to the transformer, and it is the load that determines the amount of watts, not the transformer.
What is the Difference between resistive and capacitive load?
when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load
What Device used to select amount of voltage in primary coil of step up transformer?
There is no selective device to determine the amount of voltage. A transformer is selected by the voltage available at the site for the primary and the load on the secondary side of the transformer.
What is the voltage drop across each phase if a wye connected load has a voltage of 480 v applied to it?
.24
What is the ratio of rms load voltage to mean load voltage?
The mean load voltage, in other words the average voltage, is zero in an ac system.
