Electrical Basics Class

This video is Bryan’s full-length electrical basics class for the Kalos technicians. He covers electrical theory and circuit basics.

Volts, resistance, and amps all affect the behavior of electricity in circuits. These are also critical factors in electrical safety. Watts and kilowatts come from the multiplication of the volts and amps, though not every volt-amp does work; the power factor indicates how much work the volt-amps are actually doing. Some of the volt-amps are reactive (kVAR) and don’t do the real power of watts.

Electrons move by interacting with other atoms. Substances can be conductors or insulators, and conductors have very few valence electrons, which move in and out of other atoms easily. Insulators have many valence electrons and are more stable. Insulators have high resistance, and conductors tend to have low resistance.

Circuits consist of loads, switches, and power supplies. Loads actually do things and consist of light bulbs and motors. Switches pass power and don’t do work. Power supplies can be finite, like batteries, but also include transformers that take power from the utility company. Open circuits don’t move electricity, but closed circuits create a complete path that allows electrons to move. Electricity takes all available paths, not just the path of least resistance.

Bryan also covers:
Electricity and the body
GFCIs and AFCIs
Shock and arc flash protection
Lockout/tagout
Electricity and fall hazards
Energy transfer
Resistive vs. inductive loads
Magnetism and flux
Direct current (DC) vs. alternating current (AC)
How power companies and generators work
Open vs. short circuits
“Path of least resistance”
Tripping breakers
Electrical units of measurement
Step-up and step-down transformers
Electrical frequency (hertz)
Variable frequency drives (VFDs)
Microfarads and capacitors
Parallel and series circuits
Becoming more proficient at reading diagrams

Thank you for the interesting topic. 💙💙💙

I'm 33 and I have my first day as an electrical apprentice next week. This was very helpful. Thank you!

I was repairing a Microwave oven and got shocked by the capacitor and it stopped my heart. It had been unplugged for a week. I lost consciousness and woke up on the floor.
The sudden stop when my butt hit the floor started my heart again. Discharge your capacitors with gloves on.

This guy is an excellent teacher I learned a lot I'm 62

[CubsRule]

Such a honor listening to you
I send your videos to my 23 year old son getting his feet wet in the hvac industry
Been doing for 30 years and I have tremendous respect of your skill and knowledge
Thankyou so much

I’m 30 years old. I have 3+ years in the elevator industry down in Florida. This information is helping me out a lot.

Time for me to toss out my grandfathers DIY book on basic electricity and break out a copy of Macbeth. That was a nice mix of information and humor. Great stuff.

I'm a hobbyist age 21 from South Africa and the video is awesome

[voodoo_teddy]

I have a BS and MS in electrical and computer engineering and I find this tutorial very informative. good job sir

[spencerwilliams]

I would express the utmost gratitude for sharing this content with the universe of inquiring minds. This is how we expand consciousness by enlightening each other through science informed education with a personal human touch via the internet of things 🙏

[pausaniasofithaca]

Thanks very much for the detailed explanations. This feels like a fairly comprehensive introduction to me! I am a homeowner gearing up to DIY some electrical conduit in my new garage workshop, and I wanted to brush up on what I learned in high school physics with a new focus on working with electricity safely. I'm glad I found your channel; I think this video was just the ticket!

[stillwill]

This is my favorite subscription by far. Ive relearned things I had forgotten and been set straight on things I thought I already knew for years. It will make you a much better troubleshooter.

[ermiyastesfakiros]

Thanks so much. You are the best instructor I have seen in my age.

[luis]

I’m a student, these explanations makes really easy to understand electricity, I know it is not exactly like that, but it’s enough to be introduced. Thanks

[diomedesovalle]

You are a great teacher man! I usually have to watch videos about 3 times just to start understanding everything in the video. You teach me something new and then go further with explanations and stories and relating them to things i understand completely and it sticks. Love it man i didnt even start trade school yet but i feel like im ahead with these videos^

[jameswagner]

Doesn’t matter how you get the point across or what illustrations you used to do that, the point is that people understand what you’re teaching them, don’t ever let anybody tell you anything different you don’t apologize for the way you teach ever. Just keep doing what you’re doing brother.😎🇺🇸🪖👍

[benzoluvsyou]

Everyone had a dope ass teacher like this at some point in their lives, keeps it fun but extremely knowledgeable. That Edison joke was great 😂

[godfreymgendwa]

Personally, I understand very well when you teach more than my teacher of high school. Keep it up!!

[Writtenwordspoken]

Got a good chuckle out of me with the "long circuit" you snuck in there!

[googlerodkpierrelouis]

I never regret a sec to subscribe in this channel
