Question 1 (3 points) How will you connect the ammeter and voltmeter to the devices (resistors, diode, lamp bulb) under test in the Ohm's Law experiment? 0 The ammeter will be in series with the device under test and the voltmeter will be in parallel with it. Q The ammeter will be in parallel with the device under test and the voltmeter will be in series with it. Q The ammeter and voltmeter will both be in series with the device under test. 0 The ammeter and voltmeter will be in parallel with each other and in series with the device under test. Question 2 (3 points) For Part I you will make a plot of current as a function of voltage across the resistor with the ~10 pairs of I & V you measured. Plotted in this way, taking the resistance of the resistor as R, what do we expect the graph to show? 0 A line with slope HR 0 A parabola with y-intercept R O A line with y-intercept R O A line with slope R Question 3 (3 points) In Part II the resistance of the bulb filament will change as current is passed through it. The manual recommends that you make measurements under which of these conditions? 0 Use large voltages to prevent the bulb from glowing brightly O In the dark, so that the glowing bulb allows you to read the instruments 0 Use small voltages so that the bulb does not glow brightly 0 Use small voltages so that the bulb glows brightly Question 4 (3 points) The silicon diode is a "polar" device. To observe this characteristic, we must do which of the following in our measurements? 0 Take at least 5 measurements with the diode pointed North and ~5 with the diode pointing South. 0 Take at least 5 measurements with each end of the diode connected to the positive side of the power supply. 0 Take ~10 measurements with one end of the diode connected to the positive side of the power supply. 0 Take at least 5 measurements with each end of the diode connected to the lamp bulb. Question 5 (3 points) The author of this test was taught the following mnemonic for Ohm's law : Twinkle, twinkle, Little Star Voltage equals "| times R" "what you are" "a brand new car" O "the electric potential" Note: this does not rhyme and has poor metre
