Model boundaries

The power supply and wires are ideal with negligible internal resistance.
Both components obey Ohm's law and their resistance is constant.
Measurements represent steady-state direct current.

StudyVector-authored ideal DC circuit model using Ohm's law and Kirchhoff relationships; mapped to the reviewed curriculum topics shown below.

Accessible text description

A conventional circuit diagram shows a labelled DC supply and two resistors in the selected series, parallel or potential-divider arrangement. Current arrows indicate direction and labels report the current and potential difference for each component. An optional power rail compares component power numerically and by bar length.
