Hello guys!

I have a few questions regarding my physics lab. First of all here is what the lab is about:

With that in mind I want you guys to only answer pages 5 (the 3 questions at the bottom) + 6 (the 3 questions at the bottom) and 7 (only 2 questions) , however, I included pages 4 and 6 just to help you get an idea of what the questions are asking.

Do not answer this page:

Answer this page (only the 3 questions at the bottom):

Do not answer this page (only the 3 questions at the bottom):

Answer this:

So basically any page that has this "Questions:" underlined and their are questions under it, please answer it and when you do tell me the page # of the questions you are answering. This should not take that long, high rating to whoever answers properly. Thank you !

**NOTE**

Please do not write in cursive because I cannot read it, sorry for being picky.

Lab 6: Ohm's Law Contents: I. Introduction Resistor 1 Resistor 2 IV. Conclusions I. Introduction Purpose In this lab you will investigate the relationship between current and voltage for a resistor. You will also look at currents and voltages for resistors in series and parallel. Equipment Circuit scribe kit DC Voltage source with cables Digital multimeter with probe cables Resistors More about Cutaway view of a Resistors (carbon) carbon resistor showing Instead of using bulbs in this lab, you will the cross sectional use carbon resistors. A typical carbon area of the graphite resistor contains a form of carbon, known material as graphite, suspended in a hard glue binder. It usually is surrounded by a plastic case with a color code painted on it. The graphite material provides a relatively large resistance to the flow of electric current. Color 1st band 2nd band 3rd band Reading resistor color codes The color codes on the side of the carbon resistors tell what the resistance of the Brown 1 101 resistor is Red 2 L 2 102 The first two bands are the first two digits of the resistor's value, and the third band tells you how many zeroes to add. The fourth band tells you how accurate the resistance is Yellow 4 For example, if a resistor's bands are red, Green 5 5 105 yellow, orange, and gold, it would have a resistance of 24,000 Q. The gold band Blue indicates that the resistance is good to t5%. Violet 7 7 107 Gray 8 8 108 White 9 9 109

Explanation / Answer

page 5:

Q1. as per ohms law, for a resistor, voltage=current*resistance

as resistor remains constant, if voltage increases, current will increase.

Q2. assuming resistance to remain constant (no temperature effect), voltage and current will have a linear relationship.

Q3. slope of the grap between voltage and current is resistance.

hence the slope will have a unit of ohms.

page 6:

Q1. as per ohms law, for a resistor, voltage=current*resistance

as resistor remains constant, if voltage increases, current will increase.

Q2. assuming resistance to remain constant (no temperature effect), voltage and current will have a linear relationship.

Q3. slope of the grap between voltage and current is resistance.

hence the slope will have a unit of ohms.

page 7:

Q1. I vs V will have a slope of 1/R.

so resistance of the resistor=1/slope

Q2. voltage drop across a resistor=current through the resistor * resistance of the resistor

which is the Ohm's law.
