True/False Questions?

Question

1. The length of a conductor affects its resistance.

2. In a wet cell, electrons move from the negative electrode to the positive electrode.

3. Magnetic forces are the weakest at the poles of a magnet.

4. A generator produces electric current by moving a coiled wire through a magnetic field.

5. A wet cell and a generator both produce direct current.

Thanks in advance, 10 points to best answer! [:

Answer 1

1. True (of course, R=sp.res X length/area)

2. True

3. False

4. True

5. False

Answer 2

1 True   3 IDK   4 True  5 True     Number 2 is a funny question. Ostensibly the answer is true but in the case of a car battery the poles are misnamed. If you follow the electron flow a car battery is labeled backwards.  

Answer 3

1. T, more stuff to go thru, more resistance

2. T, electrons start at the negative terminal and go to positive terminal -  that's why it's caled the negative terminal :)

3. F, mag field lines are most dense at the poles

4. T, wire moving across a mag field generate a current

5. F, generators initialy produce ac currect which can be rectified to make dc current.

Answer 4

1 yes

2 yes

3 no

4 i think
