The network shown in figure is part of a complete circuit. If at a certain instant, the current (I) is 5 A and is decreasing at a rate of 1000 A/s, then VB – VA is

A conducting square loop of side L and resistance R moves in its plane with a uniform velocity v perpendicular to one of its sides. A magnetic induction B constant in time and space, pointing perpendicular and into the plane of the loop exists everywhere. The current induced in the loop is-

6.
The SI unit of inductance, the henry, can be written as-

8.
Two circular coils can be arranged in any of the three situations shown in the figure. Their mutual inductance will be-

In a coil of resistance 100 Ω, a current is induced by changing the magnetic flux through it as shown in the figure. The magnitude of change in flux through the coil is-

10.
When current in a coil changes from 5 A to 2 A in 0.1 s, an average emf of 50 V is induced in it. The self inductance of the coil is-
