Intro to Ohm's Law & Deeper Look at Voltage in Circuits

In this video, we introduce you to the basics of Ohm's Law, one of the most fundamental principles in electrical engineering. Ohm's Law describes the relationship between voltage, current, and resistance in an electrical circuit.
We start by defining each of these terms and explaining how they relate to one another. We then move on to explore Ohm's Law in more detail, discussing how it can be used to calculate voltage, current, and resistance in a circuit.
Along the way, we use real-world examples and interactive animations to illustrate these concepts and make them easier to understand. We also discuss some common applications of Ohm's Law in electrical engineering, such as designing circuits and selecting appropriate components.
By the end of this video, you will have a solid understanding of the basics of Ohm's Law and how it applies to electrical circuits. Whether you're a student just starting out in electrical engineering or a professional looking to brush up on your skills, this video is the perfect introduction to this essential topic.

I've been wondering about different battery sizes for years. Thanks for the good explanation.

[@olinwalker8192]

Now I understand why I cannot start a car with 8 1.5 Volt AA batteries. The voltage drop would result in a much lower 'real' voltage, and therefore significantly lower amperage (linear). And thank you for your teachings. Honest, un-biased, poignant.

[@georgesadler7830]

Professor Math and Science Tutor, thank you for a practical Introduction to Ohm's Law and a Deeper look at Voltage in Circuits. The measurements of Currents/Voltage/Amps using a Digital Volt Ohm meter increases my overall knowledge and understanding of Ohm's Law. This is an error free video/lecture on KZbin TV with the Math and Science Tutor.

although it was too basic for me, cause I already know all these stuff very well but I really enjoy your lessons, there is always something new I learn from you.

[@walterwelch9894]

When I first learned electronics w e were taught the volts were E or Electromotive force, the I or Intensity or current and R for Resistance. The ohms law was E=IE and P for power in Watts was calculated as P= IE. But not pi which 3.18. Love your channel. Have a great day.

[@User-74891]

Thank you. Very interesting.

[@premkumar9608]

Appreciate you choosing subject which is need of the hour for every body.

[@brucewinningham4959]

I Agree! I also like to use the "Water Pipe Analogy" where the Voltage is Similar to the Pressure (P.S.I. or whatever measurement of Pressure you prefer to use) that Moves, Pushes or Forces the Water along inside a Water Pipe. The Amperage is the amount of Electrons flowing around a Wire

[@brucewinningham4959]

The Amperage is the Amount of Electrons (Volume) flowing "Around" a Wire or Conductor WHEREAS the Volume of Water may be rated in G.P.M.s (Gallons Per Minute) or a Fraction there of Flowing "Through" a Pipe. There are several methods of rating Water Flow. The G.P.M. Method is commonly used on the "Less Scientific" matters in the USA. My reason for empathizing "around" and "through" above is while it is commonly known that Water flows "through" a Pipe, it is NOT so commonly known that Electricity Flows "around" the Outer Surface of a Wire (NOT through it) and underneath the Insulating Material, such as Plastic, if so Equipped.

[@hemrajue3434]

I think voltage is a form of potential energy.

[@ajscain500]

This lesson is part of what course on the “ members dashboard “ ? I expected to find it under “ Engineering Circuits “ but couldn’t find it ?

[@georgeseese]

Is it possible that each battery size has a specific amount of coulombs? I think you mentioned the internal surfaces. Doesn't that equate to the presence of more coulombs, like more apple trees on a larger field? A battery then has a limited amount of these to push out. Should that value be stated on the product? Could you test your power supply to see the amps it can produce for each resistor? If it's powered from AC, I imagine it has infinite coulombs available? Thanks for your help.

[@Sc19869]

Are ampers considered the current. Why are batteries and other things measured in volts and not ampers

[@drumtwo4seven]

Nice 👍

[@MathAndScience]

Thanks ✌

[@hemrajue3434]

If connect cells in parallel, they're capable of supplying more current. I think it's same thing as using a large size battery.

The real world is perfect.. that we lack precision to match it is another thing ..

[@allanpatterson7653]

Electric current is not like water flow It is like a fluid that is compressible. That is how RF is radiated on a quarter wave antenna.

[@okaro6595]

Voltage is a hard concept. It is easy to have analogies and understand it at the surface level but what does it mean at the electron level? Voltage was used to be called tension and that word (or its equivalent) is still used in almost all other languages. The word "voltage" is strange as it means nothing like words current and resistance. The modern concept of Ohm's law is a simplified one. In reality Ohm's major contribution was just to realized the internal resistance of the battery. The batteries of the time had high internal resistance so it dominated the measurements.

[@brucewinningham4959]

I am Retired from working on the Electrical, Hydraulic & Pneumatic Systems on Drilling Rigs & other related Equipment. As you know the Well Know Fact that wiring two 12 Volt Batteries in Series gives Doubles

[@brucewinningham4959]

Sorry about accidentally hitting SEND Prematurely. So, as I was saying, wiring two 12 Volt Batteries into "Series" DOUBLES the Voltage to 24 Volts (12 X 2 = 24) while wiring them in "Parallel" DOUBLES the Amperage with the Voltage Remaining the Same. Does each Battery wired in Series have to be the same Voltage? For instance, what if I want to add a Third Battery (6 Volts) in SERIES to give me 30 Volts as in 12+12+6=30 Volts. Will that work? If so, does the 6 Volt Battery have to be arranged in a Particular Order to work Efficiently? I am sure the Engine's Alternator will need to be Upgraded for proper Recharging.
