How Optocouplers work - opto-isolator solid state relays phototransistor

Optocoupler. In this video we learn how optocouplers work and also look at some simple electron circuits you can make yourself to understand how an optocoupler, opto-isolator, phototransistor, photocoupler works. Photo transistor Correction 13:21 Upper text "220Ω" resistor should say "22Ω" calculation in lower screen is correct 0:38 Pin bottom right should be "3 Emitter" pin top right should read "4 Collector" numbering is wrong, wording is correct. Audio also contains error. ⚡🛠️ TOOLS YOU NEED 🛠️⚡ ************************************** Get this electronics book ➡️ https://amzn.to/41cCJPk Professional Multimeter -➡️ https://amzn.to/3xu2Vaw Good multimeter -➡️ https://amzn.to/3xrbuTd Professional clamp meter ➡️ https://amzn.to/4140FnK Good Clamp meter ➡️ https://amzn.to/3xqt2is Outlet tester ➡️- https://amzn.to/3kavg2l Energy monitoring plug ➡️ https://amzn.to/3SkfPl7 Battery tester -➡️ https://amzn.to/3S3fHWI Basic electronics kit ➡️ https://amzn.to/3xuLiqS MY FAVOURITE GEAR 🎥 My camera - https://amzn.to/3YCZ7Q9 🎤 My Microphone - https://amzn.to/3YYXsUC ⌨️ My Keyboard - https://amzn.to/3lBsl33 🖥️ My monitor - https://amzn.to/415BGjW 🎧 My headphones - https://amzn.to/3lN7R7u Watch these: Transistors :➡️    • Transistors Explained - How transisto...   Diodes:➡️    • Diodes Explained - The basics how dio...  ​ Capacitor:➡️    • Capacitors Explained - The basics how...  ​ Battery:➡️    • How Batteries Work - Battery electric...  ​ Voltage regulator:➡️    • 5V Regulator design tutorial - How it...   👋 SOCIALISE WITH US 👋 ******************************* 👉FACEBOOK:   / theengineeringmindset   👉TWITTER:   / theengmindset   👉INSTAGRAM:   / engineeringmindset   👉WEBSITE: Http://TheEngineeringMindset.com 👀 Links - MUST WATCH!! 👀 ******************************* ⚡ELECTRICAL ENGINEERING⚡ 👉How electricity works:    • How ELECTRICITY works - working princ...   👉Three Phase Electricity:    • How Three Phase Electricity works - T...   👉How Inverters work:    • How Inverters Work - Working principl...   👉How TRANSFORMER works:    • How does a Transformer work  - Workin...   👉How 3 Phase electricity works:    • How Three Phase Electricity works - T...   👉How Induction motor works:    • How does an Induction Motor work how ...   👉What is a KWH:    • What is a kWh - kilowatt hour  + CALC...   👉How induction motor works:    • How does an Induction Motor work how ...   ❄️ CHILLER ENGINEERING ❄️ 👉Chiller Efficiency improvements:    • Chiller Efficiency Improvements hvac ...   👉Chilled water schematics:    • Chilled Water Schematics - How to rea...   👉Chiller crash course:    • Essential Chiller Terminology HVAC de...   👉Chiller types:    • Chiller Types and Application Guide -...   👉Chillers/AHU/RTU:    • How Chiller, AHU, RTU work - working ...   👉Water cooled chiller Part1:    • Chiller Basics - How they work   👉Water cooled chiller Part2:    • Chiller Basics - How they work part 2   👉Water cooled chiller advanced:    • How Chiller works - Design Data   👉Air cooled chiller:    • Absorption Chiller, How it works - wo...   👉Absorption Chiller :    • Air Cooled Chiller -  How they work, ...   👉Chiller/Cooling tower/AHU:    • How a Chiller, Cooling Tower and Air ...   👉Chiller flow rate:    • Chiller flow rate measurement and cal...   👉Chiller fault troubleshooting:    • Chiller faults - troubleshooting   👉Chiller COP calculation:    • Chiller Efficiency CALCULATION - COP ...   👉Chiller cooling capacity calcs:    • CALCULATE Chiller cooling capacity - ...   👉Chiller compressors:    • 🔧 Chiller - Compressor Types   👉Chiller expansion valve:    • Chiller - Expansion Valve HVAC   👉Chiller surge:    • Chiller - Surge   👉Chiller condenser:    • 🔧Chillers - Condensers   👉Chiller evaporator:    • 🔧Chiller - Evaporators   👉Chiller compressor centrifugal:    • Centrifugal Compressors - Chillers HVAC   👉Chiller cooling capacity:    • Chiller - Cooling Capacity Control   🌡️ HVAC ENGINEERING 🌡️ 👉HVAC Basics:    • Fundamentals of HVAC - Basics of HVAC   👉Boilers/AHU/FCU:    • How a boiler, fan coil unit, air hand...   👉How Heat Pump works:    • How A Heat Pump Works - HVAC   👉Heat pumps advanced:    • How A Heat Pump Works - HVAC   👉Fan Coil Units:    • Fan Coil Unit  - FCU HVAC   👉VAV Systems:    • Variable Air Volume - VAV system HVAC   👉CAV Systems:    • Constant Air Volume - CAV HVAC System   👉VRF Units:    • Видео   👉Cooling load calculations:    • Cooling Load Calculation -  Cold Room...   👉Pulley belt calculations:    • Pulley Belt CALCULATIONS - Belt lengt...   👉Pump calculations:    • Pump CALCULATIONS, Flow rate, RPM, Pr...   👉Fan and motor calculations:    • Fan & motor CALCULATIONS, Pulley size...   👉HVAC Cooling coils:    • HVAC - Cooling coil + Calculations ❄️...   👉Cooling towers:    • How Cooling Towers Work   ⚗️ REFRIGERATION SYSTEMS 🌡️ 👉How refrigerants work:    • Refrigerants How they work in HVAC sy...   👉Thermal expansion valves:    • How TXV works - Thermostatic expansio...   👉Refrigeration design software:    • Refrigeration Design Software - Cools...   👉Design refrigeration system:    • How to DESIGN and ANALYSE a refrigera...   👉Reversing valve:    • Reversing valve - Heat Pump. How it w...   👉How A/C units work:    • Basic Refrigeration cycle - How it works   💻 DATA CENTERS 💻 👉Data Center cooling:    • Data Center HVAC - Cooling systems cfd
