# AC (Alternating Current)
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
A few important characteristics of an AC Signal:
|
||||||
|
|
||||||
|
## Time Period
|
||||||
|
How much time passes during one cycle of the signal (until it reaches the same point it started twice)
|
||||||
|
|
||||||
|
## Frequency
|
||||||
|
How many cycles the signal completes in a specified time frame.
|
||||||
|
|
||||||
|
## Amplitute
|
||||||
|
The maximum voltage of the signal compared to 0
|
||||||
|
|
||||||
|
## Peak-Peak Voltage
|
||||||
|
The difference between the highest and lowest peak.
|
||||||
|
|
||||||
|
## Root Mean Square Values
|
||||||
|
This helps calculating the current an equivalent DC Signal would need to provide the same amount of power.
|
||||||

In this circuit we have three major loops we can apply [[formulas#Conservation of Energy Second Law|Kirchhoffs Second Law]] to, the one on the left, the one on the right and the most outer one. We can also use [[formulas#Conservation of Charge First Law | Kirchhoffs First Law]] for the node title **A**.
|
||||||
|
|
||||||
|
$$
|
||||||
|
\begin{flalign}
|
||||||
|
&\textit{Node A:} \\\
|
||||||
|
& I_{1} = I_{2}+I_{3} \\
|
||||||
|
\\
|
||||||
|
&\textit{Left Loop:} \circlearrowright &\\
|
||||||
|
& 10_{v} - I_{1}*R_{1} - I_{3}*R_{3} = 0& \\
|
||||||
|
\\
|
||||||
|
&\textit{Right Loop} \circlearrowleft &\\
|
||||||
|
&I_{2}*R_{2} - I_{3}*R_{3} = 0; &\\
|
||||||
|
\\
|
||||||
|
&\textit{Outer Loop:} \circlearrowright &\\
|
||||||
|
& 10_{v} - I_{1}*R_{1} - I_{2}*R_{2} = 0& \\
|
||||||
|
\\
|
||||||
|
\end{flalign}
|
||||||
|
$$
|
||||||
|
|
||||||
|
Now if we would like to find out I2 for example we can use the Right Loop Formula to do so:
|
||||||
|
|
||||||
|
$$
|
||||||
|
\begin{flalign}
|
||||||
|
& \textit{Right Loop} \circlearrowleft &\\
|
||||||
|
& I_{2}*R_{2} - I_{3}*R_{3} = 0 &&| + I_{3}*R_{3}\\\
|
||||||
|
\\
|
||||||
|
& I_{2}*R_{2} = I_{3}*R_{3} &&| \div R_{2} \\
|
||||||
|
\\
|
||||||
|
& I_{2} = \frac{I_{3}*R_{3}}{R_{2}} &&| \text{ Input Numbers } \\
|
||||||
|
\\
|
||||||
|
& I_{2} = \frac{I_{3}*5}{2} &&| \text{ Simplify} \\
|
||||||
|
\\
|
||||||
|
& I_{2} = \frac{5I_{3}}{2} &&| \text{ Simplify} \\
|
||||||
|
\\
|
||||||
|
&\textit{LeftLoop:} \\
|
||||||
|
& 10 - I_{1}*R_{1} - I_{3}*R_{3} = 0&&| \text{ Replace I1 with node a} \\
|
||||||
|
& 10 - (I_{2}+I_{3})*R_{1} - I_{3}*R_{3} = 0 &&| \text{ Replace I2 with previous} \\
|
||||||
|
\\
|
||||||
|
& 10 - (\frac{5I_{3}}{2}+I_{3})*R_{1} - I_{2}*R_{2} = 0
|
||||||
|
\end{flalign}
|
||||||
|
$$
|
||||||
|
|
||||||
|
On the last formula we only have one unknown variable, which is $I_{3}$ so lets solve for that.
|
||||||
|
|
||||||
|
$$
|
||||||
|
\begin{flalign}
|
||||||
|
& 10 - (\frac{5I_{3}}{2}+I_{3})R_{1} - I_{3}R_{3} = 0 &&| \text{ Replace Variables}\\\
|
||||||
|
\\
|
||||||
|
& 10 - (2.5I_{3}+I_{3})10 - 50I_{3} = 0 && \\
|
||||||
|
\\
|
||||||
|
& 10 - 35I_{3} - 50I_{3} = 0 &&\\
|
||||||
|
& 10 - 85I_{3} = 0 && | +85I_{3}\\
|
||||||
|
& 10 = 85I_{3} && | \div 85 \\
|
||||||
|
& 0.117647059 \approx I_{3} \\
|
||||||
|
& 117.64mA = I_{3}
|
||||||
|
\end{flalign}
|
||||||
|
$$
|
||||||
|
|
||||||
|
Now lets found out $I_{2}$ aswell
|
||||||
|
|
||||||
|
$$
|
||||||
|
\begin{flalign}
|
||||||
|
I_{2} = \frac{I_{3}*5}{2} &&\\
|
||||||
|
I_{2} = \frac{0.11764 * 5}{2} &&\\
|
||||||
|
\\
|
||||||
|
I_{2} \approx 0.2941 && \\
|
||||||
|
\\
|
||||||
|
I_2 \approx 294mA && \\
|
||||||
|
\end{flalign}

# Capacitors
|
||||||
|
|
||||||
|
Capacity is measured in [[glossary#Farad|Farads]].
|
||||||
|
|
||||||
|
Capacity is calculated as follows:
|
||||||
|
|
||||||
|
$$
|
||||||
|
\begin{flalign}
|
||||||
|
& C = \epsilon r \frac{A}{4\pi d} &&\\\
|
||||||
|
\\
|
||||||
|
& \epsilon r = \text{Dielectrics relative permittivity} &&\\
|
||||||
|
& A = \text{Amount of Area the plates overlap} &&\\
|
||||||
|
& d = \text{Distance between plates} &&\\
|
||||||
|
\end{flalign}
|
||||||
|
$$
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### Important Metrics
|
||||||
|
|
||||||
|
**Size:**
|
||||||
|
Larger Capacity $\approx$ Larger Size
|
||||||
|
|
||||||
|
**Maximum Voltage**
|
||||||
|
Each capacitor has a maximum voltage that can be dropped across it.
|
||||||
|
|
||||||
|
**Leakage Current**
|
||||||
|
Capacitors are not perfect, and leak some current across the terminals.
|
||||||
|
|
||||||
|
**Equivalent series Resistance (ESR)**
|
||||||
|
The terminals are not 100% conductive, so the will have some very small resistance, (usually less than $0.01\ohm$)
|
||||||
|
|
||||||
|
**Tolerance**
|
||||||
|
The capacity is not always exact, the tolerance describes how much it could vary, usually about $\mp 1\%$ to $\mp 20\%$
|
||||||
|
|
||||||
|
## Ceramic Capacitors
|
||||||
|
- least expansive
|
||||||
|
- relative small usually $< 10\micro F$
|
||||||
|
- low current leakage and ESR
|
||||||
|
- best for high frequency coupling
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## Aluminium and Tantalum Electrolytic
|
||||||
|
- Usually polarized
|
||||||
|
- Capacity usuially $1\micro F - 1mF$
|
||||||
|
- Good for high voltage
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## Super Capacitors
|
||||||
|
|
||||||
|
- Usually can handle only low voltage
|
||||||
|
- Capacity in the range of farads
|
||||||
|
|
||||||
|
## Film Capacitor
|
||||||
|
- usually low ESR
|
||||||
|
|
||||||
|
## Mica Capacitor
|
||||||
|
- Can work in hot environments > $200\deg$
|
||||||
|
- Low ESR
|
||||||
|
- High Precision
|
||||||
|
- High Cost
