Potentaol difference, current and resistance.

Potential Difference, Current and Resistance.

1. Voltage (Potential Difference)

Think of voltage like water pressure in a hose. The higher the pressure, the more force the water has to move through the hose. Similarly, voltage is like the pressure pushing the electric charges (think of them as tiny particles) through a wire. It's what makes the electricity move.

Voltage is like the power pushing the electricity along a path, just like how high pressure pushes water through a hose.

2. Current

Current is the flow of electric charges (those tiny particles) through a wire or circuit. It's like how water flows through the hose when you turn on the tap.

Imagine a bunch of tiny ants marching through a wire; that's kind of like electric current. It's the movement of those tiny charged particles.

Current is measured in units called Amperes (or Amps for short).

3. Resistance

Resistance is like an obstacle in the path of the electric current. It's what slows down the flow of electricity.

You can think of it like a narrow part of the hose that makes it harder for water to flow through. In a wire, resistance can come from things like the material the wire is made of or even the thickness of the wire.

Higher resistance means it's harder for current to flow, just like a narrow hose makes it harder for water to flow.

Resistance is measured in units called Ohms.

So, to sum it up:

Voltage is the push that makes electricity move.

Current is the actual flow of electricity.

Resistance is like a speed bump that slows down the flow of electricity.

Remember, they all work together in a circuit. Voltage pushes the current through, and resistance resists it, affecting how much current can flow.
