Explain Ohm's law with a simple example
The short version: Ohm's law refers to the relationship stating that voltage equals current times resistance in a conductor. A quick example makes it concrete — A 12 V supply across 4 Ω gives a current of 3 A.
How to approach it step by step
Once one example makes sense, the method generalises: identify the series and parallel parts of the circuit, reduce them stepwise, then apply V = IR. In a visual interactive session the example is built on screen piece by piece, so you see which quantity changes at each step instead of only reading a final answer. Ask for a harder variant and the explanation adapts on the spot.
Worked example
A 12 V supply across 4 Ω gives a current of 3 A.
The mistake most learners make
Using the same current for parallel branches, where the voltage is shared instead.
