Document Summary
Lecture 21: electric guitars: the potentiometer is a resistor with a user-adjustable amount of resistance, the minimum and maximum resistance values are fixed during design and manufacturing. It works by taking advantage of something called a voltage divider: as we know, in a circuit with series resistors, we have individual voltage drops across each resistor. We can apply it to other types of circuits. We know that: now the value of r is not fixed, we can adjust it. In 1950, the fender telecaster was released and proved that there was a market for solid body electric guitars. The gibson guitar company, which was a well respected, high quality manufacturer was taken by surprise. They brought in guitarist les paul as a consultant on their own solid body guitar. Les paul was an inventor in addition to being a musician. While the fender designs were well received by the public, they were relatively simple, scrappy, durable and easy to repair.
