If the real circuit or an accurate simulation shows ... In general, if you set the total current to, say, four times the base current, then R2 will get three times the base current through it.

This circuit and circuit diagram contain a cell ... 3 A flows through the resistor and 2 A flows through the bulb. The total current into a junction equals the total current out of a junction.

In this episode of The Circuit, Emily Chang visits the defense entrepreneur who argues companies like his are critical to America’s future. In this episode of The Circuit with Emily Chang ...
