Copper is used in wires because it has 29 Electrons, with one in the outer (Valence) Shell. This Atom can easily escape and switch places.

# Led
|
||||
|
||||
Leds have polarity, that means they only allow current to flow in one direction. That means LED's are diodes.
|
||||
|
||||
While in resistors the relations of voltage to current is linear:

# Voltage Divider
|
||||
|
||||
## Simple Voltage Divider
|
||||
|
||||
This is sort of unrealistic because there is no current flowing out of the voltage divider on the right side:
|
||||
|
||||
![Voltage Divider](./voltage-divider.svg)
|
||||
|
||||
#### Equation
|
||||
|
||||
$$
|
||||
\begin{flalign}
|
||||
Vout & =\text{Vin }x*(\frac{R2}{R1+R2})&\\
|
||||
\end{flalign}
|
||||
$$
|
||||
|
||||
## Voltage Divider with Load
|
||||
|
||||
When the output of the voltage divider is connected to something the current drops on the output, as that something uses some of it.
|
||||
|
||||
![Voltage Divider](./voltage-divider-load.svg)
|
||||
|
||||
The load is connected in parallel to R2, so we can calculate it as a parallel resistor.
|
||||
|
||||
The new Equation:
|
||||
|
||||
$$
|
||||
\begin{flalign}
|
||||
Vout & =\text{Vin }x*(\frac{R2 || RL}{R1+R2 || RL})&\\
|
||||
\end{flalign}
|
||||
$$
|
||||
|
||||
### Example
|
||||
|
||||
Lets calculate the current in this circuit:
|
||||
|
||||
![Voltage Divider Load Example](./voltage-divider-load-example.svg)
|
||||
|
||||
1. We calculate the Resistance in the subcircuit (R2 and RL) as they are connected in parallel which means
|
||||
|
||||
$$
|
||||
\begin{align}
|
||||
\frac{1}{Re}&=\frac{1}{R2}+\frac{1}{RL} &\textit{Replace Variables}\\
|
||||
\frac{1}{Re}&=\frac{1}{100}+\frac{1}{150} &\textit{Add Fractions}\\
|
||||
\frac{1}{Re}&=\frac{1}{60} &\textit{* Re}\\
|
||||
1&=\frac{Re}{60} &\textit{* 60}\\
|
||||
60&=Re \\
|
||||
\end{align}
|
||||
$$
|
||||
|
||||
The simplified circuit now looks like this;
|
||||
|
||||
![Voltage Divider Load Example](./voltage-divider-load-example-2.svg)
|
||||
|
||||
Now we can easily calculate the Resistance in the circuit
|
||||
|
||||
With the resistance we can now calculate the current inside the load circuit by using the simple voltage divider equation:
|
||||
|
||||
$$
|
||||
\begin{flalign}
|
||||
Vout &=\text{Vin }x*(\frac{Re}{R1+Re})&\\
|
||||
Vout &=5*(\frac{60}{100+60})&\\
|
||||
Vout &=5*(\frac{60}{100+60})&\\
|
||||
Vout &=1.875v
|
||||
\end{flalign}
|
||||
