Voltage, Current and Resistance By Zaikeria Patha


Def: Potential difference in electrical charge between the two different areas in a circuit, is the force that pushes the current along through the circuit


Def: The difficulty an electric faces to pass through an object


Flow of electrons. Can only flow in a closed loop.

How These Forces Work Together

The relationship between voltage, current, and resistance is described by Ohm's law. The equation, I = V/R, tells us that the current, I, flowing through a circuit is directly proportional to the voltage, V, and inversely proportional to the resistance, R. In other words, if we increase the voltage, then the current will increase. But if we increase the resistance, then the current will decrease.

A Real Life Example

If the voltage doesn't change, but the resistance lowers, then there is less current to pass through. (As shown in the picture below)
