Question 5
4 / -1

Assertion In electric circuits, wires carrying currents in opposite directions are often twisted together.
Reason If the wires are not twisted together, the combination of the wires forms a current loop, The magnetic field generated by the loop might affect adjacent circuits or components

Question 6
4 / -1

Assertion 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.
Reason Induced e.m.f. is proportional to rate of change of magnetic field while induced current depends on resistance of wire.

Question 8
4 / -1

Assertion Self-inductance is called the inertia of electricity.
Reason Self-inductance is the phenomenon, according to which an opposing induced e.m.f. is produced in a coil as a result of change in current or magnetic flux linked in the coil.
