Question 1
This lab will require a power supply but what kind of power supply? This will be very important to the lab as the wrong power supply setting means a correctly assembled circuit will not work. (Note: depending on the edition of the lab manual this information can be found in the Basic Measurement or Simple Circuit lab write-ups.)
Group of answer choices
AC
DC
Both
Neither.
Solar
Question 2
What is Ohm's Law? [ Select ] ["Voltage", "Current", "Resistance", "Resistivity"] = [ Select ] ["Voltage", "Current", "Resistivity", "Power"] * [ Select ] ["Power", "Resistivity", "Voltage", "Resistance"]
Question 3
What is the purpose of wires in a circuit? Why do we use wires to connect power supplies to resistors or other objects on a circuit board? Why can't we just use power supplies and resistors?
Group of answer choices
To space out the circuit so the breadboard isn't overcrowded.
Wires are used to facilitate the flow of electrons throughout the circuit.
Wires are poor conductors so they will prevent anyone from being shocked.
Wires have high resistivity and so will prevent electrons from flowing and shorting the circuit.
Question 4
What are the three ways we will characterize a resistor in this lab? Consult both the lab worksheet and lab manual for this information.
Group of answer choices
Through use of Farraday's Law.
Single measurement from a multimeter.
Using the three colors on the band of the resistor to color code the value.
Use of Ohm's Law.
It will be a known value, like gravity.
Question 5
For our Ohm's Law plot, what goes on each axis to get a slope equal to exactly the equivalent resistance? Note: the lab manual instructs us to make a plot of inverse resistance (1/R), is that the best plotting method?
Y-axis = [ Select ] ["Voltage", "Current", "Resistance", "Power"]
X-axis = [ Select ] ["Voltage", "Current", "Resistance", "Power"]
Question 6
What variable should be the slope of our Ohm's Law plot?
Group of answer choices
Voltage
Current
Resistance
Resistivity
