# Resistors in Series

$R = R1 + R2 + R3 ...$

# Resistors in Parallel

***Tip:***
|
|

If resistors of the same value are in parallel the total resistance is a single resistor divided by the amount if resistors.

## Thevenin’s Theorem
|
|

States that it is possible to simplify any linear circuit, no matter how complex, to an equivalent circuit with just a single voltage source and series resistance connected to a load.

For this circuit kirchhoffs law states that:

# Glossary
|
|
||||||
|
|
||||||
## Impedance (Z)
|
|
||||||
In [electrical engineering](https://en.wikipedia.org/wiki/Electrical_engineering "Electrical engineering"), **impedance** is the opposition to [alternating current](https://en.wikipedia.org/wiki/Alternating_current "Alternating current") presented by the combined effect of [resistance](https://en.wikipedia.org/wiki/Electrical_resistance "Electrical resistance") and [reactance](https://en.wikipedia.org/wiki/Electrical_reactance "Electrical reactance") in a [circuit](https://en.wikipedia.org/wiki/Electrical_circuit "Electrical circuit").
|
|
||||||
|
|
||||||
[[formulas#Impedance in a Circuit]]
|
|
||||||
|
|
||||||
## Voltage (V)
|
|
||||||
**Voltage**, **electric potential difference**, **electric pressure** or **electric tension** is the difference in [electric potential](https://en.wikipedia.org/wiki/Electric_potential "Electric potential") between two points.
|
|
||||||
|
|
||||||
## Resistance (R)
|
|
||||||
The **electrical resistance** of an object is a measure of its opposition to the flow of [electric current](https://en.wikipedia.org/wiki/Electric_current "Electric current").
|
|
||||||
|
|
||||||
## Capacitance (C)
|
|
||||||
**Capacitance** is the ability of a component or circuit to collect and store energy in the form of an electrical charge.
|
|
||||||
|
|
||||||
## Inductance (L)
|
|
||||||
**Inductance** is the tendency of an [electrical conductor](https://en.wikipedia.org/wiki/Electrical_conductor "Electrical conductor") to oppose a change in the [electric current](https://en.wikipedia.org/wiki/Electric_current "Electric current") flowing through it.
|
|
||||||
|
|
||||||
## Current (I)
|
|
||||||
How many electrons flow through a circuit in a second
|
|
||||||
|
|
||||||
## Polarity
|
|
||||||
Means if a component is symmetric or not
|
|
||||||
Polarised means that a component is not symmetric
|
|
||||||
|
|
||||||
## LED
|
|
||||||
|
|
||||||
Anode - The shorter Leg
|
|
||||||
Cathode - The longer Leg
|
|
||||||
|
|
||||||
## Diode
|
|
||||||
## Anode
|
|
||||||
The positive end of a diode
|
|
||||||
|
|
||||||
## Cathode
|
|
||||||
The negative end of a diode
|
|
||||||
|
|
||||||
## Conventional Current Flow
|
|
||||||
When electricity was discovered people thought the electrons flow from the positive terminal to the negative, in actuality they flow in the opposite direction, but it is still possible to calculate the flow with the old way.
|
|
||||||
|
|
||||||
## Reactive Components
|
|
||||||
A component is a **reactive component** when it resists to changes in current or voltage.

# Roadblocks
|
|
||||||
|
|
||||||
## ~~ Nested tmux sessions ~~
|
|
||||||
|
|
||||||
Adding this:
|
|
||||||
```config
|
|
||||||
RequestTTY true
|
|
||||||
RemoteCommand tmux new -A -s ssh
|
|
||||||
```
|
|
||||||
to the ssh config if the specific hosts will automatically start tmux when connected
|
|
||||||
|
|
||||||
If i ssh into a remote machine with tmux started as well I have some problems:
|
|
||||||
- ~~ Duplicate tmux bar ~~
|
|
||||||
- ~~ Shortcuts don't work in remote ~~
|
|
||||||
- This works by hitting the prefix key twice, e.g. ctrl-a-a
|
|
||||||
|
|
||||||
## ~~ Debian Gnome sometimes comma key doesn't work ~~
|
|
||||||
|
|
||||||
Has not happened in a while
|
|
||||||
|
|
||||||
## ~~ Neovim shortcut to comment out ~~
|
|
||||||
|
|
||||||
Fixed this by installing the NerdCommenter Plugin
|
|
||||||
|
|
||||||
## ~~ Neovim Auto fix problems shortcut + hover window ~~
|
|
||||||
|
|
||||||
## ~~ Better git merging in Neovim, like in VScode ~~
|
|
||||||
|
|
||||||
## ~~ Copying between neovim, tmux and ssh sessions does not work ~~
|
|
||||||
## Learn how to use splits and buffers in neovim
|
|
||||||
## Fix the dictionary for neovim ltex-ls
