A.C. Ciruit without current flowing

In summary, the conversation discusses the effects of high frequency on the flow of current in an AC circuit. It is mentioned that at very high frequencies, the conductor must be designed to fit the frequency in order to efficiently transfer power. The participants also mention alternative conducting methods such as waveguides and radiation through space. The conversation ends with a question about the possibility of completely stopping current flow at high frequencies and a request for an explanation on how energy is transferred from a power generator to a house.

hi there,
In a.c. circuit, avery half circle, the current changes it direction. If u increase it, the changing rate is faster. So, this come to my mind, can u stop teh current from flowing by using very very very high frequency? That is the changing of direction of flow of electron is too rapid that it won't move at all.

As you approach high frequencies the length of the conductor is a factor and at very high frequencies the conductor must be designed to fit the frequency. When the frequency gets so high that you can't move power by shaking electrons, you use alternative conducting methods. Waveguides; glass fiber, radiation through space, etc.

Keep on chuggin !

Well, actually my question is will there be no current at all when the frequency is so high? From what u had said, does that imply that this can be happen?

Btw, how energy is transferred from the power generator far away to our house? i need some explanation on how the energy is carried out by the electrons.

Thx
 

1. What is an A.C. circuit without current flowing?

An A.C. (alternating current) circuit without current flowing is a circuit where the current is not flowing in a continuous loop. This can happen when the circuit is open, meaning there is a break in the path of the current, or when there is no voltage applied to the circuit.

2. How does an A.C. circuit without current flowing differ from a D.C. circuit without current flowing?

An A.C. circuit without current flowing and a D.C. (direct current) circuit without current flowing both refer to situations where the current is not flowing. However, in an A.C. circuit, the current changes direction periodically, while in a D.C. circuit, the current always flows in the same direction.

3. What can cause an A.C. circuit to have no current flowing?

Several factors can cause an A.C. circuit to have no current flowing. This includes a break in the circuit, a malfunctioning component, or no voltage being applied to the circuit. Other factors such as high resistance or incorrect wiring can also contribute to the lack of current flow.

4. Is it possible for an A.C. circuit without current flowing to be dangerous?

Yes, an A.C. circuit without current flowing can still be dangerous. This is because even when the current is not flowing, there may still be voltage present in the circuit. If someone were to come into contact with this voltage, they could be at risk of electric shock.

5. How can an A.C. circuit without current flowing be fixed?

The first step in fixing an A.C. circuit without current flowing is to identify the cause of the issue. This may involve checking for any breaks in the circuit, testing components, and ensuring that the correct voltage is being applied. Once the problem is identified, it can be fixed by replacing faulty components, repairing any breaks in the circuit, or correcting any wiring errors.
