Since the graph provided represents voltage and current data for resistor R, the resistance of R is 2.0 Ω
What is resistance?
The resistance of a metallic material is its opposition to the flow of electric current.
Resistance is given by R = V/I where
- V = voltage across resistor and
- I = current
What is the resistance of R?
To find the resistance of R, we take the gradient of the graph since reistance R = V/I.
So, the resistance R = ΔV/ΔI where
- ΔV = change in voltage and
- ΔI = change in current
R = ΔV/ΔI
= (V' - V)/(I' - I)
Taking points from the graph
- (I,V) = (0, 0) and
- (I',V') = (4.5, 9.0)
So, substituting the values of the variables into the equation, we have
R = (V' - V)/(I' - I)
= (9.0 V - 0 V)/(4.5 A - 0 A)
= 9.0 V/4.5 A
= 2.0 Ω
So, the resistance of R is 2.0 Ω
