Which part of the experiment involves using a graph?a.Setting up the circuitb.Adjusting the voltage on the power supplyc.Measuring the current with an ammeterd.Calculating the force based on the slope of a graph

Students are provided with an unknown resistor that has a constant resistance for all potential differences. The students are instructed to plot an I-V graph for the resistor.Which, if any, of the following are true for I-V graphs of ohmic devices?Amust be a horizontal lineBmust pass through the originCmust not pass through the originDnone of the above

Which of the following describes the type of graph you'd expect when plotting voltage across an electrical component vs current through the component, if it followed Ohm's Law?Question 3Select one:a.an inverse power lawb.Linearc.Quadraticd.Exponential

The slope of the V-I graph shall give:(a) resistance (b) reciprocal of resistance (c) power (d) charge

Question 4d The student reverses the battery connections and then repeats his measurements. On the axes below, sketch the graph that he would obtain. Part of the graph has been done for you.

Using the graph (b) for experiment 2 as given in the excel file called ‘information relevant to the online quiz’, determine, to one decimal place, the value of the activation energy for the experiment.
