What happens when lagging Power Factor changes to leading PF?
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
What will happen if 2 phase load is connected to generator?
There is no such thing as a two phase load any more. Any two legs from a three phase system are classed as single phase. If this single phase load is connected across the generator it will induce an imbalance in the output voltages of the generator. This is one reason that single phase loads on a three phase generator should be shifted around to find the best possible balance.
What is the function of capacitor across the supply to the fluorescent lamp when it is used?
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
What is the function of the capacitor in the fluorescent lamp?
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
What happens when a charged capacitor is connected across an uncharged one?
When a charged capacitor is connected to an uncharged capacitor charge flows from the charged to the uncharged capacitor until there is no net force on the charge carriers. This means that both capacitors are at the same potential, because if they were not, there would be an electric fieldand hence a force on the charge carriers of magnitudeand the charge carriers would move to equalize the potentials and reduce the electric field and hence the force, eventually to zero. Of course, as charge flows from one capacitor to the other, the total charge is conserved. In the diagram above, when switch is closed chraged flows from the top capacitor to the bottom. When charge has stopped flowing, Also, because the potentials are equal(1) Suppose then that the capacitor at top left is initially charged to potential ofand that it has capacitanceand is then connected to a capacitance Initiallystores a charge Then (3) From (1) (4) Sub (4) into (1) to get Now usefor either capacitor to findUsing it for (2) gives from A Level Physics Notes
A resistor and a capacitor are connected in parallel across a 120 v dc source determine the voltages across the resistor and the capacitor?
Since they're connected in parallel directly across the source, the voltages across both componentsare equal, and are equal to the source, i.e. 120 v DC.
IF capacitor that has been connected across a battery for comparatively long time becomes?
If the capacitor isn't punctured or failed, then it becomes charged to the voltage of the battery almost immediately after it's connected to it, and stays that way.
How a trimmer capacitor use?
A trimmer capacitor is a semi-adjustable capacitor placed across a variable tuning capacitor and pre-set to allow the main capacitor to track correctly with another variable capacitor on the same shaft. The adjustment takes out any differences introduced by the connected circuit.
What happens when heavy loads are connected to an electrical generator?
If the load is too heavy the voltage droops because of the drop across the generator's internal impedance.
Can a capacitor hold open an ac relay?
No, because as soon as a load is connected across a capacitor it will discharge. You need a continuous voltage supply across the coil of a relay to keep it energized. Yes. A large capacitor, 10000 mfd, can hold open a small relay for a few seconds, plus or minus, depending on your varibles.
Why are capacitors parallel?
Capacitors are said to be connected together "in parallel" when both of their terminals are respectively connected to each terminal of the other capacitor or capacitors. The voltage (Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then,Capacitors in Parallel have a "common voltage" supply across them giving: VC1 = VC2 = VC3 = VAB = 12V
A series LCR circuit consisting of R10 ohms and impedence 20 ohms is connected across an ac supply of 200 v rms The rms voltage across the capacitor is?
16.32 volts
What two facctors determine the capacitive reactance of a capacitor?
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
What are the initial conditions for voltage across the capacitor and current through the inductor in the dc steady state?
The initial condition is the voltage and/or current existing at the time a mathematical solution begins. Example: what happens when a resistor is connected across a capacitor? well, you say that at t=0 the resistor is connected, then after that the voltage across the capacitor is v0.exp(-t/RC), where v0 is the starting voltage, t is the time, R is the resistance and C is the capacitance. This simple solution needs only one initial condition which is the starting voltage v0 across the capacitor. Linear differential equations are common in electrical engineering and a complete solution of one (such as the example) always requires one or more initial conditions.
Why potential difference is same for each capacitive connected in parallel combination?
Because it is simple phenomenon of electricity everything(resistance,capacitor,inductor) connected in parallel holds the same voltage across the each parallel element.
Why does the voltage reading drop in measuring the potential difference across the capacitors?
Because the capacitor discharges. so voltage across the capacitor decreases.
What happens to the charge if you double the voltage across a capacitor?
In order to double the voltage across a capacitor, you need to stuff twice as much charge into it.
