0:24 Myth #1. Electricicy follows the path of least resistance.
2:24 Myth #2. When replacing a charger, you must choose a device that has a current rating that is no higher than the original.
5:11 Myth #3. When batteries are connected in parallel, the capacity increases, but when batteries are connected in series, it does not.
7:58 Myth #4. Ferrite cylinders on the cable are needed to protect against external interference. If ferrite is removed from the cable, the device will not work properly.
9:41 Myth #5. Any computer password can be hacked, you just need to hire a good specialist.
12:35 Myth #6. In diode testing mode the multimeter shows resistance.
15:05 Myth #7. The LED is current driven, not voltage driven.
20:00 Myth #8. The supply voltage of USB port is always 5v.
23:00 Myth #9. The inductor at the output of a step-down converter serves to smooth out the ripple.
25:40 Myth #10. In Europe the voltage in the wall outlet is 220v.

Learnt a lot today! Thanks Ron!
Getting a computer myth inside of an electronics myth is unexpected.
Very Nice Ron...! Keep it up....!!
thanks about the last one specifically
Battery capacity myth busting is only for spherical horse and some batteries, but not for all. In practice, capacity is rated at specific (and for marketing purposes very low) current, at least for typical non-rechargeable AA/AAA, for rechargeables in the car example can be busted maybe...). Connecting (at least cheapest AA) in series will decrease their capacity greatly due to higher current.
The penultimate one was beyond my knowledge.
thank you
Excellent video
Yeap, I know your other channel(youtube algorithms), “Major Tom Workshop”…
Good Luck=)👍
Thanks for sharing it :) Really nice channel.
@@SergeySimeonov My pleasure!
👍 Thank u
6:45 I'm still confused about this battery capacity concept !😢
15:56 what kind of power supply is that? I would like to know the reference pleasee!
To be fair car igniters won't work with any 12v supply, it needs something capable of of more than 450A for a few seconds.
I don't much about car ignitors other than that, but I do lnow that imdustrial igniters with 12000v transformers for boilers is common. So the voltage is still important to make a spark happen.
It s a frequence modulator right ?
22:39 USB 3.1 not same as USB PD 3.1
This logic is incorrect. You stated that current will go out of both paths and that the amount would be reversed to the capacity of the resistors and showed how the lower resistor passed a more amps that the bigger resistance as evidence BUT this is expected. What you have is simply A + B = C… if you have wire with 500 ma and a 50 ma then you should see 450 ma out the end of the wire. The same is true of the other wire with the bigger resistor.
What a great video that clearly deserve more views !
Thank you for the presentation
