This is prevented by self-induction in the primary winding, which opposes any change in the current strength.
Reactance is the effect of self-induction in hindering the flow of current.
This done, we break the reversed current without much effect of self-induction.
Now self-induction can be overcome by combining it with capacity.
Striking effects are produced by proper adjustments of capacity and self-induction.
The effect of the iron core is to increase the self-induction.
Its condition is discoverable, however, by the test of self-induction to currents of different direction.
self-induction is due to the action of the current upon itself during variations in strength.
In a single circuit, consisting of a straight wire and a parallel return wire there is little or no self-induction.
It is simpler and safer to join the condenser in series with the self-induction.
