What is the name of the component that stores electricity for a short period of time?
capacitor
Why the oil filled capacitor is used in permanent split capacitor motor?
An oil filled capacitor is used in (PSC) motor because the capacitor is in the circuit the whole time the machine is running. The capacitor is oil filled to cool it due to being in circuit the whole time
What is function of capacitor in 555 IC?
the capacitor and its associated resistor set the time constant.
What is ment by the time constant of a 4700F capacitor is 12seconds?
Capacitors don't have time constants. The combination of a capacitor and aresistor has a time constant. It's equal to the product of the resistance (ohms)and the capacitance (farads), and has the units of time.When the capacitor is allowed to discharge through the resistor, the voltage onthe capacitor and the current through the resistor both decrease steadily as thecapacitor empties. The time constant is the time it takes for those quantities todecrease to 36.8% (1/e) of what they were one time-constant earlier.4,700F is an enormous capacitor. But OK, if that's its real value, then in order tohave a time constant of 12 seconds, we can calculate the resistance like this:RC = 12 secondsR = 12/C = 12/4,700 = 0.00255 ohm.Now we ( I ) understand what the question is talking about !0.00255 ohm is not an external resistor connected in series with the capacitor.It must be the effective internal resistance of the capacitor itself. The performancespec of 12 seconds for the device is telling you that it has a very low internalresistance, so you can get current (energy) in and out of it fast. As a circuit-design component, it blurs the distinction between a capacitor and a battery.
What is the value of capacitor voltage and current after 5 time constant?
After 5 time constants, capacitor voltage/current will be about 99.3% of the input step change.
What is the name of the component that stores electricity for a short period of time?
capacitor
How to know that linear differential equation is time invariant or time variant?
If the coefficients of the linear differential equation are dependent on time, then it is time variant otherwise it is time invariant. E.g: 3 * dx/dt + x = 0 is time invariant 3t * dx/dt + x = 0 is time variant
What solid state component allows a mobile phone to store data even if the battery is removed for a short time?
A capacitor. (Novanet)
What solid - state component allows a mobile phone to store data even if the battery is removed for a short time?
A capacitor. (Novanet)
What is the difference between capacitor and conductor?
A conductor is a material that possesses free charge carriers capable of transferring an electrical charge. A capacitor is a discrete device in which two conducting plates sandwich an electrolytic wafer. The purpose of a capacitor is to store a charge for a finite amount of time.
Practical example for Time-invariant system?
System whose domain is not in time can be a time invariant system. Ex: taking photo to a fixed object. here domain is not in time so photo wont change with time
Is the function of a capacitor in an electric circuit to increase circuit power?
No, a capacitor in a circuit will not increase power. The capacitor is an electrical component that is used to provide resistance to a change in voltage. That's what capacitance is; it's how we define it. A capacitor (cap) can also be used to "couple" or "transfer" an AC signal in a way that isolates any DC component. Capacitors are used in waveshaping circuits in electronic circuits. The are used to store charge to "smooth" the output of a power supply. In power distribution systems, they are employed for "offsetting" the phase shifts introduced by the large number of inductive loads (like motors) on these circuits. And this things are just a start. Capacitors do not increase power in a circuit. They "give back" to a circuit, but only after "taking from" the circuit at another time. They are what is called a reactivecomponent, but they are passive. They don't "make" power and put it in a circuit.
How do you measure time without using time invariant properties of any object?
The simple answer is by using time variant properties.

Who invented the flux capacitor from back to the future?
The flux capacitor was fictional and created by screenwriter Bob Gale and writer/director Robert Zemeckis for the "Back to the Future" film series. It is a key component of the time-traveling DeLorean in the movies.
Why Laplace transform is used in analysis of control system why not Fourier?
it is used for linear time invariant systems
