Components
|
|
===============
|
|
|
|
Two types of electronic components:
|
|
1) Active: Source of energy (includes amplifying components such as transistors).
|
|
2) Passive: Cannot introduce energy into the circuit.
|
|
|
|
.. note::

|
You can design svg circuits using the `Electrical Symbols Library <https://upload.wikimedia.org/wikipedia/commons/6/6a/Electrical_symbols_library.svg>`__:

Generators
|
|
----------------

|
|
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

Equivalent resistors is simply :math:`R=R_1+R_2`.
|
|
|
|
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}`. |
