Two identical conductors of copper and aluminium are placed in an identical electric fields. The magnitude of induced charge in the aluminium will be

93. Two conductors are of same shape and size. One of copper and the other of aluminium (less conducting) are placed in an uniform electric field. The charge induced in aluminium :- (1) will be less than that in copper (2) will be more than that in copper (3) will be equal to that in copper (4) cannot be compared with that of copper ES0093

Electric Field And Potential Due To Induced Charges

Assertion (A): When two identical loops of copper and Aluminium are rotated with same speed in the same magnetic field, the induced e.mn.f. will be same. Reason (R), Resistance of the two loops are equal.

The identical loops of copper and aluminium are moving with the same speed in a magnetic field. Which of the following statements true?

Two identical loops , one of copper and the other of aluminium , are rotated with the same angular speed in the magnetic field . Compare (i) the induced emf and (ii) the current produced in the two coils . Justify your answer .

Assertion : The induced emf and current will be same in two identical loops of copper and aluminium, when rotated with same speed in the same magnetic field. Reason : Mutual induction does not depends on the orientation of the coils

Statement-1 : The induced e.m.f. and current will be same in two identical loops of copper and aluminium, when rotated with same speed in the same magnetic field. Statement-2 : Induced e.m.f. is proportional to rate of change of magnetic field while induced current depends on resistance of wire.

Asseration:The induced e.m.f. and curent will be same in two identical loops of copper and aluminium, when rotated with same speed in the same magnetic field. Reason:Induced e.m.f. is proportional to rate of change of magnetic field while induced current depends on resistance of wire.
