Step-Up Transformers

If I connect a voltage source to a step-up transformer which has a higher minimum voltage input than the voltage output as the source, will the transformer still increase the overall voltage output? Or will it not do anything since the source does not reach the minimum input for the transformer?

Any transformer is governed by the turns ratio. For example, if a step up transformer has a turns ratio of 1:10, (1 turn on the primary, 10 turns on the secondary), the voltage ratio will be V(sec) = N(sec) / N(primary) = 10 / 1. (N = turns)

Therefore, if 10 volts is applied to primary winding, 100 volts will be generated on the secondary. If 1000 volts is applied, 10000 volts would be generated (theoretically) on the secondary, however, if the voltage exceeds the insulation of the windings, this could cause the windings to short circuit and destroy the transformer. Hope this helps you. Regards, Dan
