"AC Fundamentals 241" discusses alternating current (AC) as the most common form of electrical power. AC waves can be viewed and measured on the screen of an oscilloscope. Alternating current is ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.
