In this animated activity, learners examine the fundamental operation of a logic probe that is used to detect logic signals in a digital circuit.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

The inverting amplifier configuration is presented. The closed loop voltage gain and the closed loop bandwidth formulas are explained, along with the concept of negative feedback.

In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.
