At this point, it's full-blown #NFT fever. Big thanks for the wild consistency, legend 🙌 #NFTCollectors #NFTCollection #NFTartist #eCash $XEC #CryptoLife #BlockchainHeroes Connect X pic.twitter.com/xpYZ88e8vc
Here are some topics that are often used as learning references for students, as well as the first time they are introduced to the basics of electronics:

Basic electronic component symbols
1. OHM'S LAW
Ohm's law provides information about the relationship between current, voltage and resistance.
Ohm's Law Formula
- Electric current: the movement of directed electric charges (amperes)
- Voltage: the difference in electrical pressure that causes a current between two points in a closed circuit (volts)
- Resistance: the property of a conductor that works against electric current (Ohm)
2. PASSIVE COMPONENTS
3. Active Components
- Diode,
- Transistor,
- DONE,
- UJT,
- Thyristors and Triacs,
- Relay
4. Wave Formation
Waveforms, RC Circuits, Differentiation and integration networks, Multivibrators
Introduction to Electronic Components
1. DTMF (Dual Tone Multi Frequency)
It is a microchip or IC device that functions to capture DTMF (Dual Tone Multi Frequency) signals. DTMF signals are square waves consisting of a combination of 2 frequencies produced from C and R (column and row).

2. Elco / Capacitor
If a capacitor is passed through an AC signal, resistance will arise, which is called capacitive reactance (XC), the size of which is determined by the equation:
XC = ½ πFC

Elco (Electrolytic Condenser) / Capasitor Bipolar

3. Inductor / Coil
If a coil is passed through an AC signal, resistance will arise which is called inductive reactance (XL), the magnitude of which is determined by the equation:
XL = 2 πFL
