The only problem with this is that we don't know how we would accurately measure the charge on the plastic comb, and then put increments on it. Sure, we could go "One rub against 30cm of wool" or something, however that's stupidly inaccurate.

By going to the extreme, that was the most that I was comfortable going to and I used all of the batteries that I had available. I was electrocuted by those 72V of electricity (dumb error on my behalf), and it was at something like 14A (assuming no resistance through my body, which is obviously...

How would I create such a time-varying E field? Would I need AC current? There's a link (HERE) that shows the same thing but with a balloon.

We're attempting to replicate something where we induce a charge onto the copper pipe, through the electric field, and then, similar to how a charged straw would deflect a flow of water, it would deflect the flow. Am I just completely misapplying a principle here?

Homework Statement I'm in the middle of a Year 11 open physics practical, and my partner and I have decided to attempt to find the angle of deflection of a stream of water when an electric field is placed near it. In order to do this experiment, we have a lot of 9V batteries, a voltmeter, a...
