Chapter 4

In this chapter you have learned how and why resistors absorb electrons. You have learned that they reduce the pressure of the electrons on sensitive parts and they are our first line of defense for too much pressure of voltage. You have learned the difference between mA and A as well as to read some new schematic symbols.

You have learned how to measure resistance with your multimeter and how to use the color codes on resistors to also understand how to read their values. You have learned about a most important law called Ohms law that you will use repeatedly to confirm that you are protecting your parts form too much voltage and amperage. You have learned about two artists’ applications of resistors Ross Baldwin, in measuring the resistance of humans to activate his light and glass sculpture and Diana Burgoyne who uses sound circuits and the resistive quality of pencil lead, to allow users to interact and manipulate the sound environment in the process of making abstract drawings.

You have learned about capacitors and the way to read them and classify them according to their dielectric. You have learned about the artist’s Liz Philips who used capacitance of the body to manipulate synthesizers and you have also learned about Todd Machover who uses the capacitive field of the human body to modulate sound that is part of an installation called The Brain Opera.
