====== Ohm’s Law ======

Ohm’s Law is one of the basic rules of electronics. It explains the relationship between voltage, current, and resistance in an electrical circuit. It is used to calculate how electricity flows through components such as resistors, LEDs, and wires.

Ohm’s Law is written as:

**V = I * R**

Where:\\
- **V** = Voltage (volts)\\
- **I** = Current (amps)\\
- **R** = Resistance (ohms)

This means that voltage equals current multiplied by resistance.

===== What the Terms Mean =====

**Voltage**\\
Voltage is the electrical force that pushes electrons through a circuit.

**Current**\\
Current is the flow of electricity through a circuit.

**Resistance**\\
Resistance slows down or limits the flow of current.

===== Using Ohm’s Law =====

The formula can be rearranged depending on what you need to calculate.

To find current:

**I = V / R**

To find resistance:

**R = V / I**

===== Example =====

If a 12V battery is connected to a 6 ohm resistor:

**I = 12 / 6**

The answer is:

**I = 2A**

So, 2 amps of current flows through the resistor.

===== Why Ohm’s Law is Important =====

Ohm’s Law is used to:\\
- Design electronic circuits\\
- Choose resistor values\\
- Calculate current and voltage\\
- Prevent components from being damaged

It is one of the most important tools in electronics and is used in everything from simple circuits to modern electronic devices.
