Use the model for electric current to rank the networks shown below in order according to resistance. Explain your reasoning.

I need help with the question attached to the image. Please explain with details.

Consider the combination circuit in the diagram below. What is the current through the 8Ω resistor? (Assume that the voltage drops in the wires themselves are negligibly small.) a) 1.5 A b) 0.76 A                          c) 0.55 A            d) none of these.

Two students plan an experiment that connects a bulb to an adjustable voltage source along with a voltmeter and an ammeter to measure voltage and current. They then repeat the experiment with a different sized light bulb. They recorded their data and graphed it on the axes shown below. Light bulb #1 Light bulb 82 Voltage According to the results of their investigation, which bulb had a greater electrical resistance ? O A. Light bulb #2 because it has less current at the same voltage. O B. Light bulb #2 because it had a higher voltage. C. Light bulb #1 because it reaches a higher current. O D. Light bulb #1 because It has more current at the same voltage.

In the circuit shown each of the three resistors (A, B, C) is identical. Which resistor or resistorshas the greatest current through it? a) Ab) Bc) Cd) B = C (tied for greatest current)

Plot voltage versus current for the following data.  Then, draw a best-fit line through the points, and calculate the slope.  Be sure to label your graph completely and correctly.  SHOW ALL WORK FOR YOUR SLOPE CALCULATION.(clearly show 2 points you chose on the line of your graph for slope calculation)   Voltage      Unit :V current   unit:  mA         0         2.9         1.1         8.8         3.4         25         4.8         34         6.5         40        7.5         47        9.2         58        11.3         61             Show your work below for the slope.                           Slope=
