SteveA 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
