current impulse has traversed it. If the change in flux is induced by the ...

This equation is applicable only if the damping is small; hence, if the resistance of

the

**galvanometer**circuit is small, the circuit must be opened immediately after thecurrent impulse has traversed it. If the change in flux is induced by the ...
