Question

Determine the direction the wire will deflect if the ends of the wire are connected to the terminals of an uncharged capacitor the left end of the wire is connected to the + terminal of a charged capacitor and the right end of the wire is connected to the - terminal of the same capacitor the right end of the wire is connected to the + terminal of a battery and the left end of the wire is connected to the - terminal of the same battery Determine the direction of current (if any) that can be detected in the wire if (using Front View as the reference) the wire is moved up along the page the wire is moved to the left the wire is moved into the page Determine one way (there are many possibilities, but you only need to find one) in which you can connect the wire to some device so that the wire deflects up along the page the wire deflects down along the page Determine one direction (there are many possibilities, but you only need to find one) in which you can move the wire in order to generate a current in the wire that goes from right to left from left to right

Explanation / Answer

1.

if there is no charge on capacitor it will not deflect as there will be no current flowing in conductor

it deflects down for left (+ve) right(-ve) along the page

it deflects up for left(-ve) right(+ve) along the page

2.

right to left current direction

for moving right to left current has to flow into the paper

for moving left to right current has to flow out of the paper

3.

it deflects up for left of the wire is connected to -ve terminal and right to +ve terminal of same battery

it deflects down for left of the wire is connected to +ve terminal and right to -ve terminal of same battery

4

move conductor up for current to flow right to left

move conductor down for current to flow left to right
