I am studying inductance. Can the core flux be added to or suppressed by the secondary of a transformer. I have been taught that there is only one core flux field. I understand that flux can be squeezed or attracted, I am I correct in stating; a primary current is opposed by a back current...
NoTime,
Thanks for your response. Is this the same as when the secondary voltage of a transformer is 180 degrees out of phase with the primary and the secondary has no load? We read a voltage because the induced secondary circuit is not closed, but electrons have still moved to one side of...
When a DC coil (relay) is denergized, shouldn't the collapsing field cause a current that would oppose the change in current? Wouldn't that induced current be in the same direction as when the coil was enegized? Not seeing how a freewheeling doide gets forward biased. If I apply Lenz Law...
