"In electronics, current flows from positive to negative" And thus you reignite the war between conventional flow and electron flow. It's the dirty little secret every EE just ignores. Since everything works either way, we never bothered to change that idea after it was discovered that electrons actually flow from negative to positive.
at about 19:32 "When the core of the choke is saturated energy begins to flow into the load." This is just plain WRONG! Current begins to flow into the load the instant that the circuit with supply, choke and load is completed (turned on). The *rate* of rise of the current is limited by the inductor and the rate changes when core saturates, but again, *current flow starts, at zero, the instant the power is applied.* In the circuit with the inductor in parallel with the lamp, the instant that the battery is connected the inductor current is zero. It begins to rise linearly with respect to time. In that circuit the only reason the lamp is able to turn on at all is that the inductor's resistance is high enough that it doesn't effectively short circuit the battery. In most applications the inductor is designed so that the core never enters saturation. In some circuits saturation is allowed and in fact necessary to operation of the circuit (e.g. "Royer converter"). Some of the inductors in switchmode power supplies are there for noise filtering, but the big ones are there specifically for energy storage. Several of the components shown when talking about transformers are actually "common mode inductors." Not all transformers provide galvanic isolation. An "autotransformer" does not.
you probably dont imagine how big of your contribution by making this video. Thank you.
Great video, easy to follow for people without any previous knowledge!
Thank you Sir for your very good explanation. More power to you, God bless!
You are a good teacher

You can be the FIRST!
this is half of my frist year course in ece
I also ece
Very important information about basic electronics'thank you sir.'GOD BLESS
Jesus is Lord
A donation method which includes PayPal would be fantastic.
Also 7:40, please supplement the description with the link. Thanks.
Super video.
Many thanks.
Excellent.
Wonderful and very much informative.
please explain in details each and every components in a circuit and how to find faulty components in a circuit
🎉 LOVE YOU! ❤
It's amazing!
The transformer can produce electricity if you spin a spret magnet around it, the stronger the magnet, the stonger the reaction.
Very informative.
21:32🙏🏻
Thanks ❤
Excellent ❤❤
very helpful, thank you so much.
Are you telling me Thyristor is a mosfet? It ashamed you didn’t cover the mosfet which widely use in today electronics.

Can you make a video in Malayalam plz thay would be more info for me 😞
What happened to temperature sensor of battery how you fooled the smartphone
🙏❤

TRIAC「沒介紹我」
At time 1:58 what is that 'U' in that formula? 😒🤡
U is voltage
@tomety_tcg2073 makes no sense at all... You either use 'V' or 'E' no text book has ever used the letter 'U' to symbolize Voltage 😒😒
Some books use U, considering U symbolizes potential. Voltage is just electric potential. I've seen both U and V used interchangeably
