Alexander and Sadiku's fifth edition of Fundamentals of Electric Circuits continues in the spirit of its successful previous editions, with the objective of presenting circuit analysis in a manner that is clearer, more interesting, and easier to understand than other, more traditional texts. Students are introduced to the sound, six-step problem solving methodology in chapter one, and are consistently made to apply and practice these steps in practice problems and homework problems throughout the text. A balance of theory, worked examples and extended examples, practice problems, and real-world applications, combined with over new or changed homework problems for the fifth edition and robust media offerings, renders the fifth edition the most comprehensive and student-friendly approach to linear circuit analysis. This edition retains the Design a Problem feature which helps students develop their design skills by having the student develop the question as well as the solution. There are over Design a Problem exercises integrated into the problem sets in the book.

You can check your reasoning as you tackle a problem using our interactive solutions viewer. Plus, we regularly update and improve textbook solutions based on student ratings and feedback, so you can be sure you're getting the latest information available.

You bet! Neither of the latter is practical to operate electronically; they would require a small drive motor. Light dimmers for home use employ a specific type of PWM control. Home-use light dimmers typically include electronic circuitry which suppresses current flow during defined portions of each cycle of the AC line voltage. Adjusting the brightness of light emitted by a light source is then merely a matter of setting at what voltage or phase in the AC half-cycle the dimmer begins to provide electric current to the light source e.

These rather simple types of dimmers can be effectively used with inert or relatively slow reacting light sources such as incandescent lamps, for example, for which the additional modulation in supplied electrical energy which is caused by the dimmer causes only negligible additional fluctuations in the emitted light.

Some other types of light sources such as light-emitting diodes LEDs , however, turn on and off extremely rapidly and would perceivably flicker if supplied with low frequency drive voltages. Perceivable flicker effects from such rapid response light sources can be reduced by increasing the PWM frequency. If the light fluctuations are sufficiently rapid faster than the flicker fusion threshold , the human visual system can no longer resolve them and the eye perceives the time average intensity without flicker.

In electric cookers, continuously variable power is applied to the heating elements such as the hob or the grill using a device known as a simmerstat. This consists of a thermal oscillator running at approximately two cycles per minute and the mechanism varies the duty cycle according to the knob setting.

The thermal time constant of the heating elements is several minutes, so that the temperature fluctuations are too small to matter in practice. Main article: Switched-mode power supply PWM is also used in efficient voltage regulators. By switching voltage to the load with the appropriate duty cycle, the output will approximate a voltage at the desired level.

The switching noise is usually filtered with an inductor and a capacitor. One method measures the output voltage. When it is lower than the desired voltage, it turns on the switch.

When the output voltage is above the desired voltage, it turns off the switch.

Audio effects and amplification[ edit ] PWM is sometimes used in sound music synthesis, in particular subtractive synthesis , as it gives a sound effect similar to chorus or slightly detuned oscillators played together.

In fact, PWM is equivalent to the difference of two sawtooth waves with one of them inverted.

In addition, varying the duty cycle of a pulse waveform in a subtractive-synthesis instrument creates useful timbral variations.

A new class of audio amplifiers based on the PWM principle is becoming popular.
