The potential difference points of a conducting wire does not depend between two

Question

The potential difference points of a conducting wire does not depend between two significantly on the distance between the points. a) True b) False Ohm's Law says that: a) V = IR. b) R is constant c) R increases with voltage (Circle one) How are equipotential lines placed with respect to electric field lines? a) Parallel b) Perpendicular c) At a 45 degree angle Suppose you slide a magnet towards the center of a loop of wire at a constant speed. Will a current flow in the wire? Does light travel faster, slower or the same speed in water (n 1.33) compared to diamond (n 2.42)? a. Faster in water b. Slower in water c. The same speed

Explanation / Answer

1. (a) True , it depends on the voltage increse or decrese along the wire.

2.(a) V=IR , current through object is proportional to voltage applied across the object.

3.(b) Perpendicular , since potential varies along the electric field line.

4. yes, current will flow , since there is change of flux through loop and hence voltage is generated.

5. (a) Faster in water , since , light travels faster in rarer medium.
