Free build
Free build is an interactive experiment in Circuit Builder, a free simulation from StudyFi Lab that runs right in your browser.
Build any circuit on the breadboard. Current flows only around a closed loop from the + pole of the battery back to its − pole. Ohm’s law I = U/R sets its size, and a bulb glows the brighter the more power P = U·I = I²·R it takes.
Try this: Build a loop with a battery, a switch and a bulb. Then add a second bulb in series and watch both of them dim.
