Statement-1 : A transformer cannot work on dc supply.
Statement-2 : dc changes neither in magnitude nor in direction.

Assertion : A transformer cannot work on dc supply. Reason : dc changes neither in magnitude nor in direction.

Can a transformer work on d.c. ?

Asseration: A transformer cannot work on dc supply. Reason: there is no effect of earth's magnetic field on freely falling body.

Assertion (A) : A transformer does not work on DC Reason (R) : DC neither change direction nor magnitude.

Statement-1: Magnetic field lines cannot start from a point nor end at a point. Statement-2: The line integral of magnetic field induction over a closed path is not zero.

Statement - 1 : If net force vecF acting on a system is changing in direction only, the linear momentum (vec p) of system changes in direction. Statement - 2 : In case of uniform circular motion, magnitude of linear momentum is constant but direction
