1. Ohm's Law:
Ohm's Law is a fundamental principle in physics and electrical engineering that describes the relationship between voltage, current, and resistance in an electric circuit. It's represented by the formula:

I = V/R

Where:
I = current (in amperes, A)
V = voltage (in volts, V)
R = resistance (in ohms, Ω)

2. Resistor:
A resistor is an electrical component that opposes the flow of electric current. It has a specific resistance value, measured in ohms (Ω), which determines how much it slows down the current. Resistors are used to:
Control voltage and current levels
Divide voltage
Limit current
Protect components from excessive current

3. LED (Light Emitting Diode):
An LED is a semiconductor device that emits light when an electric current passes through it. LEDs are:
Energy-efficient
Long-lasting
Environmentally friendly
Used in a wide range of applications, such as:
Lighting (e.g., indicator lights, automotive lighting)
Displays (e.g., TVs, smartphones)
Signage and advertising

When using LEDs, it's essential to:
Use a resistor to limit the current and prevent damage to the LED
Ensure the correct polarity (LEDs are directional components)

These three concepts are closely related, as Ohm's Law can be used to calculate the resistor value needed to safely power an LED!
