Voltage
Definition
Voltage, also known as electric potential difference, is the force that pushes electric current through circuits. It's measured in volts (V).
Analogy
Imagine voltage as the pressure from a water pump in a garden hose. The higher the pressure (voltage), the more water (current) is pushed through the hose (circuit).
Related terms
Current: This is the rate at which charge flows through a point on a circuit; akin to how fast water flows out of your garden hose.
Resistance: This measures how much an object resists or reduces flow of current; think about this as any blockages or kinks in your garden hose slowing down the flow of water.
Ohm’s Law: A fundamental law stating that current passing through a conductor between two points is directly proportional to voltage across two points and inversely proportional to resistance; imagine adjusting both the water pump's pressure and removing any blockages in your hose to get just right amount of water flow.
