If a step-up transformer increases voltage, then how current can be decreased ? is really the current …
A transformer can not create power so a step-up in a sense both increases the current and reduces it. If we have 10V ac supply and connect a 10 ohm resistor across it we will have 1 amp flowing in the resistor. If we now disconnect and replace it with a 2:1 step-up ...
