Ohm's Law and Circuit Basics, Simplified

Every circuit, from a torch to a phone, follows a few simple rules. Learn them once with the water-pipe picture and the rest of electronics gets much easier.

Words to know

Voltage
Think of it like water pressure in a pipe.
Current
Think of it like how much water flows through a pipe each second.
Ohm's law
Think of it like pressure, flow and pipe width.
Power
Think of it like how much work the water wheel does each second.
Voltage divider
Think of it like a waterfall in two steps.
Series circuit
Think of it like one single path through a row of rooms.
Parallel circuit
Think of it like several checkout lanes in a shop.
Short circuit
Think of it like a burst pipe.
