The value of current, `I`, flowing in a given resistor for the corresponding values of potential difference, `V`, across the resistor are given below :
`{:(I("ampere"),0.5,1.0,2.0,3.0,4.0),(V("volt"),1.6,3.4,6.7,10.2,13.2):}`
Polt a graph between V and I and calculate the resistance of the resistor.

Text Solution

Verified by Experts

The graph between V and I plotted by using the given data is shown below:

If we look at the above graph, we find that when potential difference V is 8.5 volts, then the corresponding current value is 2.5 amperes. Now,
Resistance, `R = (V)/(I)`
`R =(8.5)/(2.5)`
`R =3.4 Omega`
Thus, the resistance of the resistor is 3.4 ohms.
