WebThe variable resistor can be adjusted in order to give a range of voltages. The current can be recorded for each of the voltages and a graph of current against voltage plotted. … WebVideo transcript. we have a graph of voltage versus current for two materials and the question is which of the two materials has higher resistance in a previous video we saw …
WebIn a pure resistance the relationship between voltage and current is linear and constant at a constant temperature, such that the current ( i ) is proportional to the potential difference V times the constant of proportionality 1/R giving i = (1/R) x V. Here, the slope 1/R is nothing but the conductance. WebMar 8, 2015 · Note that the graph is that of the p.d. across the FIXED resistor against the current through it. This current is the same flowing in the whole circuit since this is a series connection. When the variable resistor has value zero, …
