Linear voltage regulator
Thus far, our power supply has:
1. Utilized a transformer to reduce the 120 volt (rms) outlet power to a lower voltage
(and higher current) ac signal that is better suited to our purposes
2. Utilized a full wave rec

Current and magnetic fields
In class, we demonstrated that two long parallel wires experience a force between them
due to the currents they are carrying. We also showed that a third wire that was carrying
no current remained motioness. The

Consider two parallel metal plates that do not touch. Like most things around us, we can
assume that the metal plates are initially electrically neutral and have an equal number of
protons and electrons. We know that electrons ar
