A capacitor is connected to earth in a circuit to provide a reference point for voltage levels. It helps in reducing noise or interference in the circuit by providing a path to ground for stray signals.Connecting the capacitor to earth also helps in stabilizing the voltage levels in the circuit.

A W pf capacitor is connected into a 240 V Hz circuit. what is the current flow in this circuit?
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
What does the red dot on the top of a 120V capacitor mean?
The red dot on the top of a 120V capacitor typically indicates the positive terminal. It is important to ensure that the capacitor is connected with the correct polarity to prevent damage to the capacitor or the circuit.
Can electric circuit b completed without earth?
Yes, an electric circuit can be completed without connecting it to earth. The circuit needs a complete path for the current to flow back to the source, so as long as the circuit is properly connected and the electrons can flow through the components, it will work without needing an earth connection.
What is a tank circuit used for?
A tank circuit is used in electronic circuits to store and transfer energy at a specific frequency. It consists of an inductor and a capacitor connected in parallel, which allows the circuit to resonate at a particular frequency. Tank circuits are commonly used in radio frequency amplifiers, oscillators, and tuning circuits.
What does the volt on a capacitor mean?
the voltage number on the capacitor indicates that the capacitor can with stand to that particular voltage across it.generally during design, the value of capacitor will be selected in such a way that this voltage rating should be double than what really we get in the circuit
A W pf capacitor is connected into a 240 V Hz circuit. what is the current flow in this circuit?
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
What ia series circuit?
A circuit in which elements are connected in series.For example in RLC series circuit resistor,inductor and capacitor are connected in series.
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.
What happen if coil and capacitor are connected in series?
series resonant circuit
But in DC ciruit there is no current when capacitor is connected?
This is because when you introduce a capacitor, the circuit is no longer a DC circuit. If you're using a multimeter see if there is an AC setting to measure the current.
What are all the components of active clamp circuit?
a switch and a capacitor which is connected in series with the switch
A circuit contains a 10 pF capacitor and a 50 pF capacitor connected in parallel.What is the total capacitance of this circuit?
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
What is the time constant of a 0.001 microfarad capacitor and a 15000 ohm resistor connected in series in a dc circuit?
The same as the time constant of a 2.7 microfarad capacitor and a 33 ohm resistor connected in series.
Is the capacitor connected in ceiling fan circuit when it is running?
No, disconnecting after providing starting torque to starting winding.
Give the derivation of Single tuned and double-tuned circuit?
The circuit has one inductor and capacitor connected in such a way that it produce the resonance condition for only one frequency. on the other hand for double tuned circuit it has more number of reactive elements and it has two tuning frequency. The single tuned circuit is of interest when the poles are imaginary, and rest of the two cases are not more interest. w=wn the time it produce the resonance and the damping factor zeta is zero and the circuit is in undamped condition.
How a trimmer capacitor use?
A trimmer capacitor is a semi-adjustable capacitor placed across a variable tuning capacitor and pre-set to allow the main capacitor to track correctly with another variable capacitor on the same shaft. The adjustment takes out any differences introduced by the connected circuit.
Why ghost power acting on a circuit?
Ghost power may be acting on a circuit if it has a capacitor or transformer connected. This will supply power long after the input has been disconnected.
