Light for Kids | Where does light come from? Learn all about light in this fun introduction video.
In this video we learn all about Light. We learn where it comes from and identify a number of sources of light. We also learn how we can change light through reflection, refraction, or by blocking light all together. It is a great video that introduces the concept of light to kids. We also invite you to download our 8 page light lesson plan for ...

AC PCB Repairing Course TRIAC (Triode for Alternating Current) एक Switching Device है जो AC Current को Control करने के लिए इस्तेमाल किया जाता है। यह AC Load (जैसे Fan, Motor, Compressor) को On/Off और Speed Control करने में मदद करता है। काम करने का तरीका: जब Gate Pin पर Trigger Signal दिया जाता है, तो TRIAC Conduct करने लगता है और AC Current दोनों Half Cycle (Positive & Negative) में पास होने देता है। इससे Load को Controlled Voltage और Power मिलती है। Use in PCB: Fan Speed Control Dimmer Circuit
