Mathematically, Ohm's Law is represented as:

$$

where:

- $V$ represents voltage (in volts)
- $I$ represents current (in amperes)
- $R$ represents resistance (in ohms)

In simpler terms, Ohm's Law tells us that the current flowing through a conductor is determined by the voltage applied and the resistance of the conductor.

**Diagram:**
Imagine a simple circuit consisting of a resistor (R) connected to a voltage source (V):

```
+ ----[ R ]---- -
| |
| |
Voltage Current
Source Flow
```

- The "+" terminal of the voltage source is connected to one end of the resistor, and the "-" terminal is connected to the other end.
- The flow of current (I) passes through the resistor from the "+" terminal to the "-" terminal.
- The voltage across the resistor is denoted as V.

According to Ohm's Law, $V=I\times R$:

- The voltage across the resistor (V) is equal to the current (I) flowing through it multiplied by the resistance (R) of the resistor.

For example, if you have a resistor with a resistance of 10 ohms and a voltage of 20 volts is applied across it: $V=20\text{\hspace{0.17em}}\text{V}$$R=10\text{\hspace{0.17em}}\mathrm{\xce\copyright}$

Using Ohm's Law: $I=\frac{V}{R}=\frac{20}{10}=\; 2A\mathrm{}\text{}\text{}$

So, the current flowing through the resistor is 2 amperes.

Ohm's Law provides a fundamental basis for understanding and analyzing electrical circuits, helping engineers and scientists predict the behavior of components and systems.
