You need 1000v to make a spark jump 1 mm, i.e. you need 100v to make a spark jump 0.1 mm.
Is it DC or AC?
It isn't just voltage that decide when and how a spark happens, it's current, voltage, the humidity of the air, pressure of the air, and temperature. There are many more, but they do not add any drastic significance.

I2C
===
1. Definisikan kecepatan clock kita, terserah kita.
Contoh: 9600 bps
"Ada 9600 bit per second; ada 9600 bit dalam 1 detik, 1 bit = 1/ 9600 second
2. Addressing
Ada 2 opsi:
1. General addressing atau specific IC addressing

1. Suatu resistor 220 OHM didalam:
1. range 200 = Unidentified
2. range 2K = .221
3. range 20K = 0.21
4. range 200K = 00.1
5. range 20M = .000
2. Suatu power supply yang tidak diketahui besarnya, diukur paralel dengan sebuah resistor:
1. range 200mV = Unidentified
2. range 2V = Unidentified
3. range 20V = 3.32V
4. range 200V = 03.3V
5. range 600V = 003V
3. Suatu arus yang tidak diketuhi besarnya, diukur secara seri dengan sebuah resistor
1. 200m = 14.6mA
2. 20m = 14.09 mA
3. 2m = 1.
4. 200 = 1 .
1. Every component have input power specification.
- Motor
- LED, voltage forwarding:
- Capacitor
- Inductor
2. Every component can be classified / categorized as INPUT device or OUTPUT device
For example INPUT:
1. Potentiometer
2. Switch: Tactile switch,
3. Temperature sensor
4. Humidity sensor
5. RFID Sensor
6. Water sensor
7. LDR (Light dependent resistor)
For example OUTPUT:
1. LED Display
2. LED
3. LED Matrix
4. 7 Segment display
5. Piezzo speaker
6. Motor
7.
3. Continuity test
- Resistor don't beep
- LED don't beep
- Potentiometer beep between midle pin / leg and right pin / leg
- Capacitor don't beep
- Transistor don't beep
- LED matrix
4. Every project can be categorized as :
1. Controller based
2. Without controller
Absorb-Unlease
Capacitor absorb energy when its positive pole connect to positive power supply.
Capacitor unleash energy when ....
