In this animated learning object, students read about the operation of a half-wave rectifier.

In this interactive object, students work 11 practice problems and solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.

In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.

Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.

In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.

Learners analyze a base-biased npn transistor circuit. A "help" screen is available.

Learners analyze a base-biased npn transistor circuit. A "help" screen is available.

Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.

Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity .
