Here's why:

* Current is the flow of electric charge through a material. Think of it like water flowing through a pipe.

* Resistance is the opposition to that flow. It's like the pipe becoming narrower, making it harder for the water to flow through.

Ohm's Law describes the relationship between these three:

* Voltage (V) is the force that pushes the current through a material.

* Current (I) is the amount of charge flowing through the material.

* Resistance (R) is the opposition to the flow.

The formula is: V = I * R

This means:

* Higher resistance leads to lower current for a given voltage.

* Lower resistance leads to higher current for a given voltage.

In summary: Resistance is the opposing force to current, limiting how much charge can flow through a material.
