Semiconductors

One of the basic building blocks of all modern electronic devices is the semiconductor. Semiconductors can conduct or block electrical current. Because of this ability, semiconductors serve an important function in everything from relays to the integrated circuits of computers.

This chapter examines diodes as well as some of the other components used to construct electronic devices, such as capacitors and resistors. Diodes allow current to flow through them in only one direction and are used in a variety of ways, including suppression of voltage spikes ("de-spiking") and converting alternating current to direct current in an alternator.

Capacitors store electrical charges and are used for electrical noise and voltage spike suppression. Capacitors are also used in timer circuits to delay turning on or off a device or system.

This chapter will examine each of the following areas:
