Well, continuing with the dynamics of the basic fundamentals of direct current, not one thing. Not what I want to focus on to give more this knowledge to the basics, is that it is also said when references are made in the current, not that When the electrons always move in the direction, this is dominated: a direct current flow, because it goes from positive to negative, so what is a representation of the voltage of a direct current in the Graph, as simple as we see there reader friend.
Well, another little thing that we should know about this very important subject, well, how unique is that the currents are reflected in the form of a flow, since it is evidenced by electrons that move through the cable or through the conductor and thanks to the amount of the charge can transport the electrons through the section of the conductor in a time interval where: the intensity I = charge / second.
Many wonder if alternating current can be converted to direct current, well, there you have it. I was going to this if there is that conversion that is evidenced when using a method called this a rectification process, this is done because it was evidenced that the rectifier is used is what is based on the application of vacuum tube, this form almost of the load of direct alternating current when the power is varied by means of diodes in the form of semiconductors, Now what happens with the polarity, good for this case, dear reader or lover of physics, the direct current was not incorporated protection against a type of change eventualities of polarity, because this as its fundamental basis is that it circulates continuously from the positive to the negative, this usually includes a circuit such as a battery or devices that use this simple form of electrical circuit in the way of generating current, Since the transport, this has an output, how about the connection can only be made in a way that prevents the inversion of the polarity, so note that it is cough maintains a very simple circuit that connects in this way that is like this with the constant, they are used when they are generated by the intensity or their power as batteries to turn on a simple light bulb to take as a very basic example.
Continuing in this order, it is the electrical power that is absorbed or emitted by a generator, an electrical device at a given instant or moment, to put it in this basic way, Okay, that is not useful to have a relationship of energy flow per unit of time or by time interval and the way the energy is also absorbed or inserted into a receiver at a certain time, that is another basic example, and another way of transforming electrical energy can be to transform electrical energy into light. Formula P = VI = V²/R = I².R.
