# Types of resistor connection used in electronic circuits

Types of resistor connection used in electronic circuits is one of the most important thing that must be known by anyone who works (repair design, build) with electronic circuits.
Are few basic types of resistor connection used in electronic circuits, so a resistor can be connected in a circuit in the following configuration: series, parallel and mixt ( series and parallel connection).
If we connect two or more resistors together we obtain an equivalent resistance that depends of all resistors connected and the connection type used .
In series type connection all resistors are connected end-to-end in a line to form a single path for electrons to flow . If the resistor are connected in series , the equivalent resistance will be the sum of all resistors ( Re= R1+R2+..+Rn ).
In the parallel connection all components are connected across each others leads , so in a purely parallel circuit, there are never more than two sets of electrically common points ( no matter how many components are connected ). There are many paths for electrons to flow (so each components have own flow current ), but only one voltage across all components. So in this type of connection the equivalent resistance will be Re=(1/R1)+(1/R2)+…+(1/Rn).
In mixt (series-parallel ) connection you will need to calculate the equivalent resistance using the equivalent resistance formula for the series and parallel connection types .
