What happens if you overcompensate with 20mF capacitor for the inductive circuit instead of 10mF capacitor which already satisfy the power factor to reach 0.95?

An inductive filter is in fact an LC circuit in which an inductor is connected in series with the capacitor. This arrangement is also known as a low-pass filter. http://www.answers.com/topic/inductive-filter

A capacitor in a circuit reduces noise because a capacitor resists a change in voltage. In combination with resistive and inductive components, even parasitic ones, a capacitor in parallel with a signal or voltage line represents a low pass filter.

because the current in a capacitive circuit leads voltage and current in an inductive circuit lags voltage. Capacitive reactance cancels out inductive reactance which is caused by motors and transformers.

What you are really looking for is total impedance not just inductive reactance. It will be different depending on how the 3 components are connected and which nodes you connect to. Consult your textbook.

Inductors and capacitors are called reactive elements in electric circuits.these reactive elements also offer resistance in the circuit termed as reactance for inductor it is wL (-j) for capacitor i is 1/wC (j) where L,C and w are inductance , capacitance and frequency of the AC source respectively when clubbed with resistance the the resultant of the resistance and reactance gives us the impedance of a circuit if the impeadence(R=0) of the circuit is of…

A mnemonic that was taught in electrical school many years ago is ELI the ICEman. In an inductive circuit, the current through the inductor lags the voltage (E) (L) inductor (I) current. In a capacitive circuit, the voltage through the capacitor lags the current (I) (C)capacitor (E) voltage. See related links below.

There's no effect since the capacitor was already faulty i.e it was like not in the circuit. Install a healthy capacitor because it will improve the power factor of the fluorescent lamp circuit thus reducing energy wasted.

An ideal inductor only has inductance. And ideal resistor only has resistance. And an ideal capacitor only has capacitance. In real life, however, all 3 have some amount of the characteristics of the others. So, in an inductive or capacitive circuit you should only have apparent power in theory, but in an actual circuit you will have resistance from the inductor or capacitor and from the conductors that connect them. This resistance is where the…

You want a power factor of 1 or 100%, which is a purely resistive circuit. If you have a motor or some other inductive load in a circuit the total voltage and total current in the circuit will not be in phase (phase shift), your power factor will be less than 1. By adding a capacitor (180 degrees out of phase with inductive load) to the circuit that has a capacitive reactance equal to the…

A capacitive circuit will more readily pass an AC current, while an inductive circuit will pass a DC current.

A small capacitor can be part of an integrated circuit.

In general the length of the leads contributes only a negligible amount to the capacitance of a capacitor. However at high enough frequencies excessive lead length can contribute an undesirable amount of parasitic inductive reactance, causing problems in circuit operation.

What happens to the current in a circuit as a capacitor charges depends on the circuit. As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as…

Yes. For a condition called 'series resonance', if the resistance of the circuit is low compared with the inductive reactance and capacitive reactance, then the voltage drop across the capacitor can be VERY much higher than the supply voltage.

Inductive. Voltage (E) leads current (I) in an inductive (L) circuit and current (I) leads voltage (E) in a capacitive (C) circuit. (ELI the ICEman)

an inductor an electromagnet the inductive part of a resonant circuit the inductive part of a ripple filter circuit in a power supply an RF blocking device etc.

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"…

when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"

Any circuit using a capacitor will not work if the cap is short-circuited.

Current lags voltage in an inductive circuit. The angle by which it lags depends on the frequency of the AC, and on the relative size of the inductance compared to the resistance in the circuit.

All are considered passive because they cannot amplify a signal. Of the three, the resistor is the passive component. Both the capacitor and inductor are reactive components. Capacitors store energy through electrostatics. Inductors store energy through electromagnets. Voltage lags current by 90 degrees in a capacitive circuit. Current lags voltage by 90 degrees in an inductive circuit.

A parallel capacitor increase the capacity of the portion of the circuit in which it is installed.

Yes, you can connect a polarized capacitor to a direct current. Make sure you get your polarization is correct. A non polarized capacitor can be connected in a DC circuit as well. "Non Polarized" just means it does not matter which side of the capacitor is positive. If you attempt to connect a polarized capacitor in a DC circuit backwards, you will know when the capacitor explodes.

paper capacitor

Capacitors store electrical charge. Imagine we have a capacitor. At time 0 seconds we connect a DC voltage across the capacitor - immediately as the voltage is connected the capacitor is at 0 volts and the maximum current (relative to the circuit resistance) flows. At this extreme the capacitor can be treated as a short circuit, so for high frequency AC volts we should treat a capacitor as being a short circuit. As time passes…

A generator is a highly inductive device with low resistance. Capacitors are, well, capacitive. when you have an inductor near a capacitor, you can get ringing. This is known as ferroresonance. The capacitance and inductance form an LC tank circuit, which causes excessive overvoltages. Generators are typically high impedance grounded, which contributes to ferroresonance issues.

An open circuit, by definition, has no continuity, therefore there is no current flow. A failed capacitor in an open circuit would have absolutely no effect.

Inductive. Used to remember this by "Eli" the "ice" man. "(e) Voltage (l) (Inductive circuit) (i) current", the ,"(i) Current (c) (capacitive circuit) (e) voltage, man.

A Capacitor allows a time delay for the circuit (imagine that the capacitor is a well and the circuit cannot continue until the well is full). In other words, Capacitors stop the circuit from passing a specific point for a time period.

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

When the terminals of a capacitor are connected together, the capacitor will discharge, returning to a zero potential state. Capacitors resist voltage change, meaning that if the capacitor is in a circuit that has zero voltage potential, the capacitor will eventually achieve zero potential. If the capacitor is in a circuit that has a 5 volt potential, the capacitor will seek and attempt to maintain that 5 volt potential (provided that the capacitor is rated…

The electrical term reactance speaks to the "resistance" to AC in a circuit (though it isn't resistance) because of the presence of inductive and capacitive components in that circuit. Reactance can be either inductive or capacitive, and in each case we investigate, energy is taken from the circuit and then returned to the circuit, but at different times. Additionally, in the case of inductive reactance, the energy is stored in the form of a magnetic…

a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit

An RC circuit is a circuit in which the source is AC or alternating current and within that circuit there is a resistor and a capacitor Answer An R-C circuit is one that has resistance and capacitance. As these are naturally occurring, you don't necessarily need a resistor and a capacitor!

the current lags behind the voltage by 90 deg. phase angle ( if the circuit is pure inductive ,otherwise the angle depends on the value of inductance)

the capacitor is store the charge and used as back up

In general, no. You need to use the correct capacitor as designed for the circuit.

A resistive load puts no reactive power load on the supply. An inductive item like a motor which has windings and a magnetic field loads the supply with reactive power as well as real power. Reactive power is power that flows from the supply for half of the ac cycle and flows back for the other half. Thus it puts a current load on the supply without drawing power, so it wastes power in the…

If one capacitor is connected to circuit it is know as single tuned circuit.if two capacitor is connected to circuit it is know as doubled tuned circuit.

These are capacitors that are connected in a circuit in parallel with the load. A circuit with low, lagging (inductive) power factor (pf) can be improved by those static capacitors by decreasing the circuit's inductive reactive power (wasted power consumed for magnetic induction of motors) reducing it's pf to almost unity (1). A circuit with low power factor means it consumes more power which is actually not being used or wasted. Putting a static capacitor…

inductive capacitive resistive

When there is no load on a circuit with a capacitor in the line, no current will pass. The capacitor, if charged, will remain charged until a load is put on to the circuit at which time it will discharge its designed output voltage.

Capacitor bank is use to control the power factor of the load, because there is many inductive load in the circuit which is the cause of the lagging P.F, so we use the capacitors to maintain the P.F to the unity, the capacitor have the nature of the leading P.F that's way the resultant P.F of the load's lagging and the capacitor's leading current is near to the unity, and the unity P.F has very…

Yes. In an inductive reactive circuit the voltage leads the current by 90 degrees. For an AC circuit, the voltage will follow a cosine wave form and the current will follow a sine wave form.

I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.

In electrical or electronic circuits, impedance can be said to have capacitive or inductive components. Capacitors cause capacitive impedance, and coils (chokes, transformers, loudspeakers, etc.) cause inductive impedance. A capacitor is said to be a reactive component in an AC circuit because it holds charge, then releases it, causing a phase shift in the output current. This phase shift in current equates to a phase shift between current and voltage. Reactive power is defined as…

The phase angle between voltage and current in a purely inductive circuit, under ideal circumstances where there is no resistance at all, is 90 degrees.

Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.

because without using capacitor or resistor in a circuit,it cant be complete.Resistor is used to protect the circuit by giving a certain amount of voltage.Capacitor is used to charge and discharge purpose.

R for resistor, C for capacitor. RC circuit is a circuit built with a resistor and a capacitor. This circuit will have a typical pulse response that looks like exponential decaying and a typical resonance frequency.
