Study the following data and write which set of value should be rejected so that ohm's law holds good for the remaining set of values. Draw the graph and find out the mean resistance
Volts(V):- 2.5 5.0 10.0 15.0 20.0 25.0
I(A) :- 0.1 0.2 0.3 0.6 0.8 1.0
please give the answer its important..

if the appliance is following straight line in V-I graph then it must be ohmic at that temperature,( other factors should also be constant) .
if any doesn't follow then it is no ohmic device.
So use this concept.
plot graph and observe which data should be rejected to hold ohm's law good.
Otherwise u can also calculate the slope of the straight line .(y axis Voltage and x axis current)
if any one deviates, reject that one.
for mean resistance
(25+25+33.3+25+25+25)÷6=26.38ohm.
if any doesn't follow then it is no ohmic device.
