Um Circuito Simples Que Ensina Muito Sobre Eletrônica

In this video, we continue our study of the electric mosquito swatter, now focusing on the circuit that generates the high voltage. In Part 1, we showed what's inside this seemingly simple device: the battery, the capacitive charging source, and the transformer that generates high voltage. Now, in Part 2, we'll understand how this high voltage is rectified, stored, and made available at the output. Here you will see, step by step: How the high-voltage winding of the transformer works. The role of the diodes and capacitors at the output. Why this circuit is not a classic voltage doubler. How the capacitors accumulate charge over the cycles. Why the voltage reaches thousands of volts, but with extremely low current. This type of circuit was not designed to supply power, but rather to: store voltage, store energy in the capacitors, generate a quick and effective shock. All explained in a simple, practical, and visual way, without complicated formulas. ⚠️ Important Notice: Despite the low current, we are talking about high voltage. Do not attempt to assemble or test this type of circuit without proper knowledge and precautions. 👉 If you haven't watched Part 1 yet, I strongly recommend starting there: [   • Um Aparelho Simples Que Ensina Muito Sobre...  ] If this type of explanation helps you: leave a like, share, and tell us in the comments if you want to see other real circuits explained this way. ___ 🔧 Want to support the Eletrônica Brothers channel?
