Question

Slope of v-i graph is 45 degree then resistance is equal to

Answer 1

The slope of VI graph give us the resistance. In IV graph, Current is at y-axis and potential is at x-axis. The reciprocal of the slope of IV graph shows the resistance.

Answer 2

Answer:

Resistance is 1.27 ohm

Explanation:

The VI graph predicts the variation of current along the change of voltage.

The X axis represent the voltage while the Y axis represents the current.

As the formulae,

V = I R

The slope of the graph represents the resistance of the conductor.

R = $\frac{V}{I}$ = tan Ф

Thus the resistance is given by ,

$\frac{1}{tan(theeta)}$    =  cot Ф

which represents the resistance of conductor.

Here,

45 °  = 0.78539 ( in radians)

$\frac{1}{0.78539}$  =  1.27325 ohm

The resistance is found to be 1.27 ohm.
