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 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
When a series circuit comprising of a resistor and a capacitor is connected to an AC supply the current will?
In a series circuit with a resistor and a capacitor connected to an AC supply, the current will lead the voltage due to the presence of the capacitor. This is because the capacitor will initially act as a short circuit for high-frequency AC signals, allowing current to flow through it before charging up. As the capacitor charges, the current will decrease, and the phase relationship between the current and voltage will change accordingly.
How do you control lights using scr?
silicon controlled rectifires are like transistors,in this function.we can adjust load(lights)by adjusting bias voltage by a potentiometer(veriable resester). ANSWER: It could be an SCR but most likely is a TRIAC that conduct both +/- of the AC cycle. These devices have the ability to conduct if a gate current is present. So some kind of delay is used to fire the triac at certain angle of the ac The delay is a resistor capacitor network where the resistor changes the RC time constant for firring
Which angle is not to be changed while drill grinding?
The clearance angle, also known as the relief angle, should not be changed while drill grinding. This angle is crucial for allowing the cutting edges to clear the workpiece effectively and prevent binding. Maintaining the correct clearance angle ensures efficient cutting and enhances the lifespan of the drill bit. Adjusting other angles, such as the point angle or lip angle, can be beneficial for specific applications, but the clearance angle must remain constant.
How capacitor and resitor in a circuit effect the phase of input voltage?

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 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 does ohm's law works in a resistor circuit?
Ohm's law states that voltage is resistance times current. In a resistor circuit, knowing two of voltage, current, or resistance, you can calculate the third.Actually, this applies to any circuit, be it resistor, capacitor, or inductor. Ohm's law still applies - it just gets more complex when the phase angle of current is not the same as the phase angle of voltage.
In a capacitor circuit load angle is?
Negative.
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.

In a series circuit with a resistor and a capacitor connected to an AC supply, the current will lead the voltage due to the presence of the capacitor. This is because the capacitor will initially act as a short circuit for high-frequency AC signals, allowing current to flow through it before charging up. As the capacitor charges, the current will decrease, and the phase relationship between the current and voltage will change accordingly.
What is the phase angle of an ohm inductor in series with an ohm resistor connected to a 5 KHz source?
You need to provide values of resistor and inductor etc to find the phase angle.
What is mechanical angle?
It is the angle that can be changed
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.
Phase limit in induction furnace?
It means the Phase anlge is not matching with control board phase angle or more capacitor connected in the furnace line. we have to Remove some tank capacitor.
When did Dead Angle happen?
Dead Angle happened in 1988.
