Hello everyone, today I am going to explain about electricity and electric circuit. 00:00:01
First we have to note about electric current and it is the movement of electrical charges through a conductor. 00:00:10
It is the flow of electrons through a circuit. 00:00:18
So these electrons go from the negative point to the positive one, from the minus to the plus of a cell. 00:00:21
At the same time, we can tell apart between direct current, which goes in one direction, and alternating current, that varies in value and direction. 00:00:30
To do something useful with electric current, we need to put electrical components into the circuit, 00:00:43
such as a cell, the energy source to supply the electric energy to the circuit, 00:00:51
a conductor, like a wire, a receptor, for example a bulb to transform the electrical energy into light energy, 00:00:59
and a control element, like a switch. 00:01:09
There are several options to connect the receptors. 00:01:13
The most important ones are series circuits, when the receptors are linked one after the other. 00:01:20
The main drawback is if one of them is broken, none of them works. 00:01:29
On the other hand, in parallel circuits, all the first terminals of the receptors are connected to one point 00:01:37
and the second terminals are connected to another point, so if one of the receptors fails, the other works. 00:01:47
This is the case of the appliances at home. 00:01:59
To finish, one important content that we must learn is the Ohm law, and it says that current 00:02:05
intensities is directly proportional to the voltage and inversely proportional to the 00:02:15
resistance. 00:02:22
So guys, I hope this explanation is useful to understand the elasticity unit. 00:02:23
Bye bye. 00:02:31
