1) An Ohmic device is one that obeys Ohm’s Law. According to your data, are carbon resistors Ohmic devices? Support your answer with references to your graphs and/or equations.(adsbygoogle = window.adsbygoogle || []).push({});

2) When a typical circuit is switched on, the net displacement of electrons along a wire is about 1 mm per second. If electrons have such a low net speed, why do lights and devices appear to work instantaneously when switched on?

R = V/I

1) The lab portion is a bit ahead of lecture so I'm not totally sure about this one. Using Ohm's law i was able to calculate an experimental value with a percent error of only 2%, but is that enough evidence to prove it is an Ohmic device?

2) This one I'm very lost with due to the lack of knowledge about circuits (since lab is ahead of lectures). Not really sure where to begin.

Thanks!
