Resistance of the resistor = 1.96 Ω
Explanation:
as we know that
y = mx + c is equation of line
m = Tan( angle amde with x axis)
Here at x axis is V ( Voltage)
& y axis is I ( current)
=> I = Tan27° V + c
as it passes through 0 , 0
hence
=> c = 0
=> I = Tan 27° V
=> V/I = Cot27°
=>. R = Cot27°
=> R = 1.96
Cot27° = 1.96
Resistance of the resistor = 1.96 Ω
