I must point out that just because you can plot a straight line on a graph of voltage and current does not mean that the slope of the line is R. The slope could be 2R+5 or cos(R).
The previous poster raises a good point that Ohm's law is a worded statement not originally stated in a formula.
How was Ohm's law ever verified?
To verify it you need to measure the current, voltage and resistance over a range of values and show that ohms law satisfies their solution. The catch is that typical ohmmeters do not measure resistance, they measure current and voltage and use ohm's law to find...
Part of my assignment is to find the stresses in each member of a truss bridge, but unlike the problems I have been taught before, this involves a load between the joints of the bridge. Me and my group are using the method of joints to find the forces acting through each member, the problem is...
