Hello, a simple question: a circuit with a DC source and a

In summary, the conversation discusses the concept of charging a circuit with a DC source and a capacitor. It is explained that there are no energy losses during the charging process because there is no conduction in the circuit. However, when an AC source is used, work is done by the source because charge is moved to the capacitor's plate. It is also mentioned that sometimes, seemingly "stupid" thinking can lead to great inventions.

hello,

a simple question: a circuit with a DC source and a capacitor (assume no voltage loses due to the cables etc..)
there wille be nog energy loses during the charging of it, because there's no conduction in the whole circuit, so no work is done by de DC source

now assume a AC source, in this case also no work is done by the source ?

is this all correct ?

grtz

How does a capacitor get charged with no conduction of electricity? I think you are confusing the final static equilibrium system with the process of charging.

yes indeed, during the process of charging work is done by the source, because charge has been moved to the capacitors plate !

stupid tginking of me ! :blushing:

:rolleyes: I'm pretty sure stupid thinking, almost always precedes smart thinking.:smile:

but those thing are quit fundamental...
but you're rigth great inventions were made by some crazy ideas

htank you !
 

1. What is a DC source?

A DC source, or direct current source, provides a steady flow of electrical current in one direction without any variation. It is commonly used in electronic circuits to power devices.

2. What is a circuit?

A circuit is a closed loop or path through which an electrical current can flow. It typically includes a power source, such as a DC source, and various components like resistors, capacitors, and inductors. Circuits are used to control the flow of electricity and perform specific functions.

3. How does a DC circuit work?

In a DC circuit, the DC source provides a constant voltage, which causes a current to flow through the circuit. The flow of current is controlled by the components in the circuit, which can either resist or allow the flow of electricity. This allows for the circuit to perform a desired function.

4. What are the advantages of using a DC circuit?

DC circuits have several advantages, including the ability to provide a constant and reliable power source, simpler design and construction, and better compatibility with electronic devices. They are also more efficient and can be used for a variety of applications, from small electronic devices to large power grids.

5. Can a DC circuit be converted to an AC circuit?

Yes, it is possible to convert a DC circuit to an AC circuit by using a device called an inverter. An inverter can convert the direct current from a DC source into alternating current, which can be used to power AC devices. However, the conversion process can result in some energy loss and may require additional components in the circuit.
