1
Named after Greg Ohm, Ohm's law is arguably one of the most important and fundamental equations to understanding electricity.
2
In a nutshell, Ohm's law showcases us the relationship between resistance, current and voltage in electricity.
3
The power of Ohm's law comes in the ability to shuffle around the equation to calculate for either voltage,
4
current or resistance in this lesson we will learn how to use these equations for our calculations
5
and when to use which equation
6
and how to mash up different equations together for our calculations now in case you don't know what current voltage
7
and resistance is you can learn these terms by comparing water to electricity in
8
that case water pressure can be compared to electrical voltage the
9
volume of water flowing can be compared to electric current and the restriction of water flow can be compared to electrical resistance.
10
Now going back to the equations, if the equations that I showed you earlier felt like too much to remember,
11
you can simply refer to an Ohm's law triangle to derive the appropriate equation for your calculation.
12
To use a triangle, firstly cover up the value that you want to calculate for.
13
Now look at the other two values that are not covered up.
14
If these two variables are side by side, that means they will be multiplied to get the value that you desire.
15
If they are on top of each other like this, they will be divided in that appropriate order like so.
16
Let's do a quick example here with the circuit.
17
Let's say we know the value of the resistor but we don't know how much current is flowing through the circuit.
18
We can use Ohm's law to derive the current as this.
19
When an electronics device follows these rules and equations, it is called an ohmic device and when it doesn't follow these rules and equations, it's called a non -ohmic device.
20
Examples of non -ohmic devices are semiconductors such as transistors and diodes.
21
Now we have already seen how we can use Ohm's law and shuffle it around to either calculate for resistance,
22
current or voltage, but you can also substitute other equations into Ohm's law making it even more flexible for your needs.
23
For example, we can substitute the V or I variables here in Ohm's law and get equations such as these.
24
This makes calculations for your circuits and projects easier and more flexible.
25
Due to us being able to substitute other equations into Ohm's law, we can use something like an Ohm's law pie chart, as you can see here, to do more advanced calculations.
26
Again, these are not new equations per se, but rather equations that are formed by shifting and merging multiple different equations to make them easier for our calculations.
27
This is thanks to the beauty of algebra.
28
And that's it for this video.
29
Thanks for watching.

Understanding Ohm's Law: A Real-World Science Scenario

The video breaks down Ohm's Law, a fundamental concept in electricity, using simple analogies and practical examples. Imagine explaining this to a classmate or troubleshooting a circuit—you’d need clear, concise language to describe relationships between voltage, current, and resistance. Phrases like "shuffle around the equation" or "mash up different equations" make complex ideas accessible, mirroring how we simplify concepts in everyday conversations. This scenario is perfect for english speaking practice, as it blends technical terms with casual explanations, helping you communicate complex ideas fluently.

Useful Chunks & Collocations to Memorize

  • "In a nutshell" – A natural way to summarize key points (e.g., "In a nutshell, Ohm's Law links voltage, current, and resistance").
  • "Shuffle around the equation" – Describes rearranging formulas (e.g., "You can shuffle around the equation to find current").
  • "Mash up different equations" – Means combining formulas for flexibility (e.g., "Mash up Ohm's Law with power equations for advanced calculations").
  • "Cover up the value" – Refers to using the Ohm's Law triangle (e.g., "Cover up the value you need to calculate to find the right formula").
  • "Follow these rules" – Distinguishes ohmic vs. non-ohmic devices (e.g., "Devices that follow these rules are called ohmic").

Your Shadowing Challenge: Master Clarity & Pace

The shadowing technique is a proven way to improve pronunciation, intonation, and fluency. Here’s your task: Watch the video again, pausing after each 10-second segment. Repeat the speaker’s words immediately after, mimicking their rhythm and emphasis. Focus on phrases like "the beauty of algebra" or "makes calculations easier"—notice how the speaker stresses key terms. For extra practice, use a shadowing site to record yourself and compare it to the original. This "shadow speak" exercise trains your brain to process and reproduce English naturally, turning technical jargon into conversational fluency. Try it daily, and you’ll soon feel more confident explaining complex ideas in English.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
