WebAn IV graph shows that the line is straight and goes through the origin, as shown in the image below: IV graph for a fixed resistor. The current is directly proportional to the potential difference (voltage) as the graph is a straight line through the origin Filament Lamps For a filament lamp, current and voltage are not directly proportional WebA 12 V battery is in series with an ammeter, a 2Ω fixed resistor and a 0 − 10Ω variable resistor. High-resistance voltmeters P and Q are connected across the variable resistor and the fixed resistor, respectively, as shown. The resistance of the variable resistor is changed from its maximum value to zero. 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. … chillicothe cefcu
