Excellent content as usual sir!

Subscribed for sure.
Great videos for a newbie like myself.

this is really well done you should do op amps and mosfets
good success

[@hamzakourta4509]

is rated voltage just the mirror image of power rating like (U = √(P x R)) or is it a different property determined by dielectric strength and similar stuff?

[@dave.F0X]

Does it matter if a higher wattage rating is used? My electronics project book recommends getting 1.5W resistors, and yet none of the projects need more than 0.5W resistors.

[@andriykopiychuk3307]

So, why then, when I connected 10K 0.25W resistor to the 12V battery it got hot enough to burn my finger? According to the calculations: 12v/10000 Ohms = 0.006Amps; And then 0.006A*12V = 0.072Watts. While resistor tested was 0.25W - way more then 0.072Watts required. Why is it getting melting hot?

sir good pm, i ask 8 pcs led lights what resitor we use??? Thank you

[@TheElectroBench]

Try googling “LED resistor calculator” - you should be able to find lots of online calculators that will help you work this out. You will need to know the supply and forward voltage etc for your circuit/LEDs.

[@ejohnalarcon2805]

ah, thank you sir

Rrrright.....
You totally lost me when you were like suddenly...
E = MC squared math crap..... lol....
