Understanding Voltage, Current, and Resistance

The secret to all electronics is a simple fight between three forces. First,

you have Voltage. Think of it as the pressure pushing electricity through a wire.

Then there's Current, which is the actual flow of that electricity, like water rushing through a pipe.

Finally, you have Resistance, the component that tries to slow that flow down.

Ohm's Law is the simple rule that governs this battle: The push (Voltage) is equal to the

flow (Current) multiplied by the struggle (Resistance). This single idea, V = I × R,

is the fundamental principle behind every circuit, from your phone charger to the entire

power grid.
