matrix match

Column I

1. A fully discharged capaciter battery of constant Emf. is connected to the end of the wire
2. The wire is rotated about one end of its length with constant angular velocity in a uniform magnetic field perpendicular to the
plane of motion.
3. The wire is bent into a semicircular ring aned placed in a constant electric field with its diameter perpendicular to electric field
4. A A.C.current source is conncted to the end of the wire.

Column II
a) A constt. current flows thru the wire
b) Thermal energy is generated in the wire
c) A constt. potential diff. develops between the ends of the wire
d) Charge of constt. magnitude appear at the ends of the wire.
