How does a DC Circuit work?

DC circuits are powered by direct current sources, which are power sources that generate a potential difference (voltage) between two points. If we were to separate some electrons from their atoms and then connect the electrons, through conductors, back to their original atoms, we would have a DC circuit.

Power

DC Circuits. Power. Power is the rate at which work is being done. Work is performed when a force causes a mass to be displaced. A familiar example of work involves a weight. When a mechanical force is used to lift or move the weight, work is done. In the circuit of figure below, find the power dissipated as heat in the resistor. Example

What are the components of a DC Circuit?

DC Circuits are made up of two main things: components, and conductors. Components are the ''blocks'' that make up the circuit. Power sources, resistors, capacitors, LEDs, and transistors are examples of common components. Conductors provide paths for current between all of the components of the circuit.
