Question
1. Suppose that you measure the resistance of a resistor using a volmeter, a current meter, and a battery. Suppose that the volmeter reads 0.2% high and the current meter reads 0.3% low. What will be the percent error in your measurement of resistance.
2. Why did you have such a large percent difference in the resistance of the lamp filament with the two different applied voltage? What physical condition of a conductor must remain constant for ohm's law to apply?
