What is the formula for phase angle?

Phase angle is defined as the angle by which the load current leads or lags the supply voltage in an AC circuit. There are numerous ways to calculate a circuit's phase angle, so there is no 'formula' as such. For example, if you know a load's resistance and impedance, or its true power and apparent power, then you can use basic trigonometry to calculate the phase angle, and so on.

What is the Difference between resistive and capacitive load?

when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load

DC blocking in a transistor is achieved by?

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.

How capacitor and resitor in a circuit effect the phase of input voltage?

A capacitor and a resistor has no effect on the supply voltage; however, this particular load combination will cause the load current to lead the supply voltage by some angle termed the 'phase angle'.

What happened if the capacitor is in line when there is no load?

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.

When does a capacitor discharge?

A capacitor discharges when it releases the stored electrical energy it has accumulated. This typically happens when the capacitor is connected to a circuit or load that allows the energy to flow out of the capacitor.

What will happen to phase angle if the the value of capacitor is increase?

in a series RC circuit phase angle is directly proportional to the capacitance

How do you decide KVAR rating of capacitor bank?

The KVAR rating of a capacitor bank is typically determined by the reactive power (KVAR) demand of the system that needs to be compensated. This can be calculated by conducting a power factor study or analysis to determine the required amount of capacitive reactive power to bring the power factor to the desired level. The KVAR rating of the capacitor bank should be selected to meet this calculated KVAR demand.

A series RC circuit will have a phase shift between 0 and 90 degrees?

If there are only a resistor and a capacitor in the circuit, then the phase shift will indeed be between 0 and 90 degrees. When the resistor and capacitor are in series, the phase shift will be negative when the capacitor is connected to a source voltage and the resistor is the load. The phase shift will be positive when the resistor is connected to the source. The lower the values of R and C, the higher the frequency bandwidth.With the resistor and capacitor connected in series and the two parts connected to a current source, the phase shift will be negative. At high frequencies, the output voltages is lower, and the circuit appears as a very low impedance. At low frequencies, the circuit looks more like a resistor. Again, the phase shift will be between 0 and 90 degrees.CommentThe correct term is phase angle, not 'phase shift'. By definition, the phase angle is the angle by which the load current leads or lags the supply voltage. For an RC circuit, the current leads the voltage, so the phase angle is a leading phase angle.

What effect a capacitor has on a supply current on an inductive load?

it will improve the power factor... The angle between voltage and current will decrease depends on capacitor value.

Why is circuit current reduced when a capacitors added to the circuit?

In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.

How you select capacitor for filtration?

A: The load is the factor demanding filtration including the maximum ripple required for the circuit to operate reliably

Is capacitor a part of integrated circuit?

A small capacitor can be part of an integrated circuit.

What happens if the resistor in RC circuit is removed and the capacitor is directly connected to power supply?

If by power supply you mean a voltage source, it really won't matter that the resistor is removed. The voltage source will provide infinite current, instantly charging the capacitor so that the capacitor's voltage is equal to the source.Alternative AnswerIf you are referring to an a.c. circuit, then a load current will continue to flow with its value being determined by the capacitive reactance of the circuit, and the resulting phase angle will lead the supply voltage be very close to 90 degrees.

What is the formula for phase angle?
