Capacitor?
capacitor is a power cell used to generate electricity in the motor of ceiling fan
Why is a capacitor called a capacitor?
Due to its storing capacity.it charges for a some time and then discharges when power supply is removed.
How can you store a different amount of charge in a capacitor?
Power = V*I Power = (V) * (C*dV/dt) To store more / less power / charge, charge the capacitor with a greater / smaller voltage (make sure the cap is rated for at least as much as the voltage you are charging from, though).
What is Soft charge resistor?
Just makes the capacitor charge at a slower rate, reduces input power.
Why does a capacitor keep its charge after the supply is disconnected?
Yes, it can. Then you can use the charge to power something else. :)
Why are bleeder resistors connected across the capacitors?
A: As the term says it bleeds the capacitor charge when power is removed . Because capacitor are like a water tank in its case it will store power for quite some time therefore a bleeder resistor is required. This power can be a detrimental factor to the circuit or sometimes even fatal to humans if it is assumed that shutting off power will totally remove the power.
Why power rating of capacitor is reactive in nature?
A capacitor is composed of metal plates. Voltage is applied to one, which causes electrons to build up on the other. This is reactive in nature, thus a capacitor is reactive. It stores a charge, and releases this charge when the voltage decreases.
Why you use capacitors in power supply?
You use a capacitor to store electrostatic energy. You use an inductor to store electromagnetic energy. You use a resistor to dissipate electrical energy.
What type of component holds its charge even after the power is turned off and the device is unplugged?
Capacitor
Can a capacitor be gradually charged by lesser capacitors?
A: SURE capacitors in parallel will share the charge. But don't expect a .0001 mfd capacitor to charge a 1000 mfd capacitor. It just does not have the power stored to effectively charge the 1000 mfd. EXAMPLE 1litter of water cannot fill up a 5 litter container
Can capacitor store charge from ac source?
Yes. A capacitor stores charge from any source, including AC.The difference between DC and AC, however, is that the capacitor will be constantly changing in charge, in step with the AC. Due to the nature of the capacitor, the current through the capacitor will lead the voltage by some amount, depending on capacitance and resistance. {In the ideal case of a perfect capacitor, conductors, and AC power source, the current will lead the voltage by 90 degrees phase angle.}This is called capacitive reactance.Another way for a capacitor to store charge from an AC source, of course, is to place a rectifier diode in front of the capacitor. This, then, becomes an AC to DC converter.
What does a power supply capacitor hold?
when the current supply to the capcitor it can store or hold little amount of charge
