Electric Current & Circuits Explained, Ohm's Law, Charge, Power, Physics Problems, Basic Electricity
This physics video tutorial explains the concept of basic electricity and electric current. It explains how DC circuits work and how to calculate voltage, current, and electrical resistance using Ohm’s law. In addition, it shows you how to calculate the electric charge and the number of electrons flowing through a wire at any given point. In addition, it has a few examples and practice problems on electric power, cost of electricity in Kwh and other stuff as well. It provides visual drawings, equations, and formulas as well as the units of common variables that you’ll encounter when dealing with electricity. It discusses the difference between conventional current and electron flow. The unit of electric current is the ampere or amps for short. The unit for resistance is ohms and for voltage is volts. 1A is 1C/s or 1 coulomb per second. Electric current is the rate of electric charge flow. Charge represents the quantity of electrons in the case of metal conductors. The unit of power is the watt which is 1 Joule per second. Power is the rate at which energy is transferred. Equations used include V=IR, P=VI, and Q=It.

Use triangles when using equations, a lot easier
I’m in grade 8 so we haven’t had this stuff yet! So I’m just LEARNIN yk! That moment when u wanna become an astrophysicist LMAO my teacher’s shook
Thanks alot…. Digital learning is far more better to understand rather than reading and learning… Thank you
Thank you so much
this is so much better than reading my text -_-
this guy is the best
My god i have a test tomorrow 😂😂😩😩
So you’re telling me at 13:43, if you spend 11 cents per KW an hour, if you operate it for a month it will only cost 14 cents? Sorry but my mind… is blown.
Why are you using calculator
who’s using this during an online test
We love you man <3
we love you the organic chemistry tutor
tnx
WHAT THE HELL IS ELECTRIC CURRENT???

👍
Love this guys content
If 360 coulomb charge flows a conductor in 3 minutes, calculate the current flowing through a circuit.
For question 3, do you not have to convert to hours from seconds? Isn’t a watt energy per second
Great video. Useful .
My go to channel whenever I have an exam the next day!!
I love u
Why p=vi
You’re truly a life saverrr
Me Tomorrow
Tell me:: please
Device name you writing📝📝✍
Fantastic video. Increase the voltage will AUTOMATICALLY increase the current
which will increase the available Power (watts) given the same resistance. Ohms law.
I should have paid more attention in physics class
yessss
I have been trying to understand this since i was at the ordinary levels. Haven’t watched it yet but i have no doubt is just what i need.
thank u sir.
OGT take the wheel
You made the concept so easy
There are several factors in learning circuits. One plan I discovered which successfully combines these is the Gregs Electro Blog (google it if you’re interested) without a doubt the best course that I’ve heard of. look at this interesting resource.
Online class is waving
on the 3rd problem why is it R=80 ohms and not 8? pls explain
my physics sir is hot trash and i have an o level exam in May <333 hoping this saves my Ass
i love you
How v=IR? Because if v=IR so resistance will directly related with v and you said that the voltage inversaly related with R .I hope to clear that point for me and thank you for this
amazing explain
えと。。。。ありがとごうざいますう
Umm he sounds handsome lol
all hac is elect current .enter on apps app is elect manip hac inf in u c ? misc
kill app kill hac app force stop
usual
apps with gps pubc typ settins bac ground dsta etc
turn off any butns apps not use
jam adds like to use as psi
Can you help me with a problem?
This video basically covered 2 chapters in my textbook! Damn helpful and thankful 🙌👏🙏
Can someone please explain to me why 0.11$ is the cost of 1KWh but 0.14$ is the cost of one month
Anyway I like his lessons
very good
I’m an old engineer who hasn’t had the need for this stuff for years due to the kind of assignments and opportunities that were offered to me out of school. Now I’m refreshing my old self. It’s so weird to see stuff that I learned 20 years ago just pop back with a little nudge from these videos. A great way to learn or relearn.
You’re A Life Saver!
thanks pal, good videos, your maths could be more simple but they work, thanks again!
Thankyou sir, because of you, I got an A in this topical test 😇👍
Finally i understood this lesson🙂
