Ohm's Law Concept Map Explained
An Ohm's law concept map shows how voltage, current and resistance depend on each other in an electrical circuit. Georg Ohm's relationship states that voltage equals current multiplied by resistance, V = IR. The map groups the quantities, their units (volts, amperes, ohms), the rearranged forms of the formula, and examples of series and parallel circuits.
- Core quantities: voltage (V), current (I) and resistance (R), with units
- Formula forms: V = IR, I = V/R and R = V/I
- Power link: how P = VI relates to Ohm's law
- Circuit examples: series and parallel resistor calculations
- Limits: when Ohm's law holds for ohmic materials
Use the map to revise the formulas and practice the rearrangements before an exam. Build a personalized version from your own course notes with CogniGuide.

Ohm's Law Questions Answered
Answers to common questions about the law, and how to build your own map.
What does Ohm's law state?
Ohm's law states that the voltage across a conductor is proportional to the current through it, with resistance as the constant of proportionality. It is written V = IR, where V is in volts, I in amperes and R in ohms.
Does Ohm's law apply to every material?
No. It holds for ohmic materials, such as most metal conductors at a steady temperature, where resistance stays constant. Diodes and many semiconductors are non-ohmic, so their current does not scale linearly with voltage.
Which files can I use to make my own map?
You can upload PDF, Word (DOCX) or PowerPoint (PPTX) files, text or Markdown files, or images of your notes. You can also type a topic instead.
Can the map become a quiz?
Yes. Free accounts can create up to 5 maps a week, and the map can be turned into a quiz to test yourself on the formulas and relationships.
