How you have calculated 1 small division value. Why you divide it by 40

@physicswithaliva9791 6 ай бұрын

To cover atleast 60% of the graph, I have done this. Here 0.1A = 40 division ( we have chosen it) Then 40 div = 0.1 A 1 div = 0.1/40 A =0.00250A Then plot (reading/ 0.0025 )

@iqbalrangrej7189 5 ай бұрын

you are explaining wrong the graph of current vs voltage is worong. which we can find (current)by determine one of the value (voltage)are on y axis means current in y-axis and voltage in x axis because we are determine the value of voltage and take the value of current. The resistance of the given wire is equal to the reciprocal of this slope. This statement is given in the journal of class 12th

@physicswithaliva9791 5 ай бұрын

If you draw voltage vs current then resistance=slope If you draw current vs voltage then Resistance= reciprocal of slope You should understand these basic concepts.
