Here's why:

* Resistance: Resistance is a property of a material that opposes the flow of electric current. The higher the resistance, the harder it is for current to flow.

* Voltage: Voltage is the driving force that pushes the current.

* Current: Current is the flow of electric charge.

The relationship between these three is described by Ohm's Law: Voltage = Current x Resistance.

In simpler terms:

Imagine a river flowing downhill. The path of least resistance is the easiest route for the water to flow. Similarly, electricity will always choose the easiest path to flow, which is the path with the least resistance.

This principle is crucial in understanding how circuits work and how electricity travels through different materials.
