Unformatted text preview: ts 4  ­12  ­6 the number of zeroes, so 104 is equal to 10 x 10 x 10 Farads or 0.1 x 10 Farads or 0.1 micro Farads (0.1 μF, sometimes written uF). There are several different types of capacitors, each with its own characteristic shape. Some different types are shown in Figure 4. The 1000 Ω potentiometer (sometimes called a "pot") (Figure 5) is the rectangular or cubic blue device. It is a variable resistor; the value of the resistance can be adjusted with a small screwdriver or adjustment tool (supplied in lab kit). There are two different types of pot in the lab kit. The rectangular one requires 15 – 20 turns to go from zero resistance to maximum. The cubic one requires only about ¾ of a turn. The 100 mH inductor (Figure 6) is the blue cylindrical device with two wires. It is marked in black with LJ 410. Inside the blue plastic case is a coil of enameled copper wire. Real (non ­ideal) inductors typically have a resistance of several ohms, as well as an ideal inductance. The 9V battery connector is the black plastic cap with two snaps mounted on it and a couple of wires coming out of its side. The snaps fit with the snaps on the top of the 9V battery. The red wire is from the positive terminal of the battery, the black from the negative terminal. For the 1.5 V battery, the connector is a black plastic case. Comments • For each procedure set up the circuits and record your data and the answers to questions on a separate sheet(s) of paper and hand it in at recitation section when the lab is due. For procedure 5, you will also have to bring your breadboard with designated circuits on it to your recitation section the week the lab is due. Some...
