If you have an inductor device which receives switched currents, it is a good practice to cancel out the inverse induction voltage with a simple diode in reverse direction, which protects the rest of the circuit from high voltage.

My little joule thief mod outputs 40KV 250uA. If you want to see it, ask.

In a single phase motor,, especially with starting coil,how does a capacitor change phase angle or to be precise,what does A capacitor do..

Thank you so much!Your video is so amazing that I'd never heard before,these knowledge helped me a lot.I'm an engineer and I recognized myself as an engineer at least always until I read your video. How to give some support to you by RMB format?

11:40 - Wouldn't high-voltage spikes also be present on the secondary, placing hundreds of volts across the base-emitter junction?

13:41 , I think when the magnetic field collapses on the secondary, the transistor will be reverse biased so no base emitter current (blocked)

@@1rstcar Oops! I forgot about that resistor (it was present earlier in the video).

Dear Sir, i have been watching your videos for a long time, i like your videos too much and your explanation is also very nice, i have learned a lot of stuffs from your videos, i didn't want you to make a particular video of something yet, now i need a single transistor buffer circuit explanation, i want you to please make a video of single transistor buffer circuit , if we use a darlington transistor instead of ordinary transistor for an emitter follower circuit, what is the advantages and disadvantages, please discribe for me dear sir 🥰🥰🥰😍😍 🙏🙏🙏

Thank you for coming back to the real science and not that arguing with popular videos on the youtube that I really didn't like (I mean that period when there were more videos like that on your channel , arguing with other opinions about some subjects but it wasn't a scienctific debate! ) and which in my opinion didn't have any sense. This kind of video like here has sense!

The atrio-ventricular (AV) node in our hearts is a natural relaxation oscillator that acts as a blocking oscillator. The sino-atrial (SA) node in the left atrium is the pacemaker oscillator which is the relaxation oscillator that sets the heart rate. The natural rate of the AV node is lower than the rate of the SA node and is driven by the SA node. The AV node is triggered by the signal it receives from the SA node and then passes the electrical activity across into the network of Purkinje fibers in the left ventricle and beyond which trigger the various muscles in the heart to contract in the proper order. The electrical activity reaches back to the AV node, but because it is "dead" for a certain period of time after firing it acts to block the reentrant activity. In cases where the AV node is damaged in some way the reentrant activity triggers it again leading to arrhythmias.

I am a 64-year-old Finnish man and it is nice to study RF technology. it would be nice if the tutorial videos were purely in English. PS. Shall we sauna in the summer?
