When a wire of resistance $15 \mathrm{ohm}$ is connected to the terminals of a battery of emf $18\mathrm{V},$ the terminal PD is $15\mathrm{V}.$ The terminal resistance of the cell is

The radius of curvature of the path of a charged particle in a uniform magnetic field is directly proportional to:

A given number of identical cells connected in parallel give large current through an external resistance when the external resistance has value

Two rectangular iron rods $A$ and $B$ has equal length breadth and thickness. But $B$ has a hole drilled at its centre. They are magnetised by placing them in the same magnetising fields then

When the current flowing in a coil is $0.5$ A, the flux linkage in another nearby coil is $0.002$ weber. The coefficient of mutual induction for the pair of coil is
