Answer to Question #2395 in Mechanics | Relativity for Johanna

Question #2395
A variable voltage supply was connected in a series circuit with a 10 ohm resistor and an incandescent bulb. Assume that the incandenscent bulb has a linear relationship between its measured voltage and current (i.e. Ohm's Law: V=IR).
Table: Measured current and voltage across a light bulb.
Voltage (V): 1 ; 3.5 ; 5.6 ; 7.2 ; 9 ; 10.5
Current (mA): 60 ; 275 ; 450 ; 550 ; 640 ; 820
1. Draw a graph to represent this data. Calculate the slope of this graph, and use this value to determine the resistance of the globe.
2. Describe an alternative method (that doesn't use a graph) to analyse the measured voltage and current data to determine the resistance of the globe. Use this method and compare its result to the value calculated using the graph technique.
