 Components

 Two types of electronic components:
 	1) Active: Source of energy (includes amplifying components such as transistors).

 Generators
-^^^^^^^^^^^^
+----------------
 
 .. include:: esl.rst
 
 There are two important generators to know:
 	1) Current generators |igen_c| that strive to maintain constant current on his terminals. Arrow must point towards the current direction (`source <https://ultimateelectronicsbook.com/labeling-voltages-currents-nodes/>`__).
 	2) Voltage generators |igen_v| that strive to maintain constant voltage on his terminals.

+Resistors
+-------------
+Two ways of connecting resistors: 1) series 2) parallel

+Series

+Parallel

+Equivalent resistors is :math:`\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2} \Rightarrow R = \frac{1}{\frac{1}{R_1}+\frac{1}{R_2}}`.
+With only two resistors, it is simply :math:`\frac{R_1R_2}{R_1+R_2}`.
