Current is the continuous flow of electrons. Current is almost the same thing as voltage except current deals with the flow of electrons and voltage deals with electrical charge.


Voltage is the potential difference in electrical charge between two different areas in a circuit. For example batteries and generators are two of the most common sources of voltage that power our daily lives. We'll look at them in detail to see how they work.


Resistance is the difficulty an electric current faces to pass through an object. For example on a microscopic level, electrons moving through the conductor collide, (or interact) with the particles of which the conductor (metal) is made. when they collide, they transfer kinetic energy. The electrons therefor lose kinetic energy and slows down. This leads to resistance.


Power is the rate of doing work. For example, a rock climber takes an abnormally long time to elevate her body up a few meters along the side of a cliff. On the other hand, a trail hiker (Who selects the easier path up the mountain) might elevate her body a few meters in a short amount of time.

Current, Voltage, Resistance, Power

Current, voltage, resistance, and power are all similar because they all are apart of electricity and without current, voltage, resistance and power there wouldn't be any thing called electricity. The difference between current, voltage, resistance, and power is that they all do different things when it comes to electricity. For example, current deals with the flow of electrons, voltage deals with the potential difference in electrical charge, resistance deals with challenges an electrical current faces, and power deals with the rate of doing work. They are all the same and different in their own little way.
