(a) (b) (c) (d) You are given a voltmeter, micro-ammeter, a 12 volt DC battery, enough connecting wires, a variable resistor, a switch, and a resistor of 100 ohms. Draw the symbols of all these electrical components and label them After connecting an appropriate circuit, several readings are obtained by changing the voltage in the circuit. Explain how you would do this? The readings are recorded in Table 1, as shown below. Redraw this table in your answer book and calculate the value of R for each set of V and I. Now find the average value of R. Voltmeter reading V [volts] 2 4 6 8 10 Table 1: Values of V and I Resistance of the resistor [Ohms] Ammeter reading 1 [Amperes] 0.010 0.019 0.030 0.041 0.052 Average Resistance value Plot a smooth graph of V against / and determine a value of R from the graph.
