If I-V GRAPH is straight line then resistance is ohmic and reciprocal of slope gives value of resistance.
y=mx + c here m (slope) is .00142 so
Resistance is 1/m =1/.00142= 704 ohm

When verifying Ohm's law, you plotted a current-voltage graph based on the measured data for an unknown resistor, as shown in Fig. 2. Its resistance is estimated to be a. 0.00006 Ω b. 0.00142Ω c.16.7kΩ d, 704 Ω
A group of students in a previous class produced the following voltage vs. current graph for two different light bulbs and two different resistors. Unfortunately, in their exuberance at finishing the activity, they forgot to write down which line represented which device. Based on your understanding of Ohm's law, determine which lines represent light bulbs and which lines represent resistors. Explain your reasoning. Which line represents the resistor with the greatest resistance?
1 A repelling force must occur between two charged objects under which conditions? a. charges are of unlike signs b. charges are of like signs c. charges are of equal magnitude d.charges are of unequal magnitude 2 Two point charges are 4 cm apart. They are moved to a new separation of 2 cm. By what factor does the electric force between them change? a.2 b. 1/2 c.4 d. 1/4 3. By mapping the equipotential lines, you can draw a. the charge b. the electric field...
The voltage drop (V) across a resister is proportional to the current (I) through the resister. Ohm's Law: V = IR. Wednesday's laboratory expernnent attempts to verify Ohm's Law and measure the resistance (R) of a resister Ammeters and voltmeters potentially have offsets, resulting in a constant added to the equation: V = IR + VO If voltage satisfying this equation is plotted against current, the result is a line. With voltage on the y-axis and current on the r-axis,...
Part A A group of students performed the same "Ohm's Law" experiment that you did in class. They obtained the following results: Trial ΔV (volts) I (mA) 1 1.00 20.5 2 2.10 42.0 3 2.90 57.5 4 3.90 78.0 5 4.90 98.0 where ΔV is the voltage difference across the resistor and I is the current traveling through the resistor at the same time. (a) Analyze the data. (You will not submit this spreadsheet. However, the results will be needed...
