in a graph a current vs. voltage, is the resistance = to the slope or 1/slope?

current on the y-axis and voltage on the x-axis
2006-10-19 04:29:29 · update #1
it depends on how you labeled your axes:
1) If voltage is the x-axis and current is the y-axis, then the slope = y/x
or Current/Voltage = 1/R (use v=IR to solve -> R=V/I, 1/R=I/V), thus resistance = 1/slope
2) If voltage is y-axis, and current is x-axis, then slope = voltage/current = resistance, thus R = slope in this case
Hope this helps

If current is on the x axis then resistance is the slope;
if voltage is on the x axis the slope is 1/v
V = IR
y= mx + b

Depends on whether you have current or voltage as your x-axis.
R=V/I
slope = dy/dx
So, if current (I) is your x-axis, resistance(R) = slope.
if voltage(V) is your x-axis, resistance(R) = 1/slope.

according to ohms law
current is directely propotional to voltage
resistance=voltage/current
so, resistance is equal to slope

I don't know your graph,but it can be calculated easily.
E=IR
I=E/R
R=E/I
Try it it is simple
