Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...

Build students’ confidence with circuit diagrams and deepen their understanding of how electricity moves through different circuit types. This lesson introduces series and parallel circuits through ...

This Power Tip shows you how to do a quick conversion of parallel-to-series complex impedances (and vice versa). It also shows that a graphical representation of this transformation as a function of ...

Previous tutorials have described that resistors may either be connected as a series circuit or a parallel circuit where the currents and voltages are obtained using Ohm’s Law. To produce more complex ...

A clear, structured lesson comparing how current, potential difference and resistance behave in series and parallel circuits. Students calculate total resistance for components arranged in different ...
