I think i have it then. are the comments correct on the graphs attached. Basically the centre one is upside down, and all in all its a weird way to represent ohms law. or are they all correct, but its just a weird way to explain it |
| agehall:
Your comment on the second graph is wrong. Just do the math - U=I*R. Let's set U to 10 and see what happens: With R=1 => I=10 With R=5 => I=2 With R=10 => I=1 Not exactly linear but since there are no units on the graph, you can assume it just shows you the general idea - as resistance increases, current has to go down to maintain a constant voltage. |

If I recall the name correctly the graph of R vs current should be a 'hyperbola', not a line. Any small section of it will look a linear relationship, but R approaches infinity when current is 0, and current is 0 when R approaches infinity. |
