Question
Okay I am completely lost on where to even begin on this one. please someone help me get started and better understand what it is asking for. Thanks in advance!
For this exercise, we will examine the dependence of the current flow through a resistor when the voltage across the resistor is varied. The circuit we will be using is shown in Figure 1. A dc power supply is connected to a variable resistor which has a sliding contact point. A resistor with an unknown resistance is then connected to the sliding point of the variable resistor so that the voltage (V) across the resistor can be changed by sliding the contact point on the variable resistor. An ammeter (A) is connected in series with the resistor so that the amount of current flowing through the resistor can be determined at the same time.
Your task is to read the voltage and current for each setting of the variable resistor by clicking on the links and enter the values in the table. Note there is no current flow when the voltage is zero. Click onreading a voltmeterfor an example of how to read the voltmeter andreading an ammeterfor an example of how to read the ammeter.Use the same number of significant figures as shown in the examples.
Explanation / Answer
It is for the verification of Ohm's law.
Here the variable resistor at which their is a slider is a potential divider
i.e. it provides different values of potential difference across the resistor while the source voltage (5V DC) is same
for reading values first check their range by the red dot
accordingly see the scale on the meter and read values such that it matches with the range
