# 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?

there would be no problem with this == == The inductive circuit has a 'lagging' power factor. If you over-compensate with too much capacitive reactance, you could go over the top (past 1.0) , and end up with a leading power factor that may even be numerically worse than when you started.

### What is the inductive circuits?

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…

### What effect does a capacitor have on an ac voltage?

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.

### Why is active power observed in capacitive and inductive circuits during practical experiments?

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…

### Describe in brief the type of power factor improvement system?

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…

### What happens to the current in a circuit as a capacitor charges?

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…

### 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"…

### Why resistor and capacitor and inductor are passive components?

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.

### Can a non polarized capacitor be connected to a direct current circuit?

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.

### Why capacitor behave as open circuit against alternating current?

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…

### Why capacitor banks are not recommend with generator sets?

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.

### What will happen if two terminals of capacitor are shorted?

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…

### What is reactance?

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…

### What tends to decrease reactive power in a 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…

### What are static capacitors?

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…

### How capacitor banks maintains the power factor?

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…

### Why capacitor is said to be a reactive component?

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…
