Interpretation of electromagnetic interactions
Electrical circuits
The fundamental elements in any electrical circuit are:
Voltage
Current
Endurance
An electrical circuit is a system in which current flows through a conductor in a complete path due to a potential difference.
Series circuit
The conductive elements are connected one after the other, in such a way that, if the circuit is opened anywhere, the current is completely interrupted.
The connection of batteries in series is made by joining the positive pole of one with the negative pole of the other and so on according to the desired voltage.
The potential difference or total voltage applied to a series circuit is immediately distributed among its elements.
The voltage in any of these will have a value such that it allows the flow of current in the circuit through the resistance of said element.
In a series circuit, the sum of the voltage drop across each element is equal to the total applied voltage.
The total or equivalent resistance of a series circuit is equal to the sum of all its resistances.
Parallel circuit
The conductive elements are separated into several branches and the electric current is divided in parallel between each one of them; thus, by opening the circuit in any part, the current will not be interrupted in the others.
The connection of batteries in parallel is made by linking, on the one hand, all the positive poles and, on the other, all the negative poles.
In a parallel circuit, the elements operate independently. Therefore, if one of the branches is disconnected or opened, the rest will continue to work.
In a parallel circuit, the more branches there are, the more paths there are for current to flow. Therefore, the total or equivalent resistance that determines the flow of current decreases.
Resistor connection
In series
When resistors are connected in series, they are joined at their ends one after the other, so that the intensity of the current passing through one is the same in the others; therefore, if it is interrupted in one, it is also interrupted in the others.
By connecting two or more resistors in series, the equivalent resistance can be calculated with the mathematical expression: Re = R1 + R2 + ... + Rn
In parallel
When the resistor is connected in parallel, its terminals are joined at two common (external) posts that connect to the power or voltage source. In this connection, the electrical current is divided into each of the branches or derivations of the circuit.
By connecting two or more resistors in parallel, the equivalent resistance (Re) of the combination can be calculated with the following mathematical expression:
1/Re = 1/R1 + 1/R2 + ... + 1/Rn
Mixed
When you have a mixed connection of resistors it means that they are grouped both in series and in parallel.
The way to solve these circuits mathematically is by calculating the equivalent resistance of each connection, either in series or in parallel, so that the circuit is simplified until the value of the equivalent resistance of the entire electrical system is found.
