An increase in load (equivalent to a decrease in resistance*) causes an increase in load current. This increases the internal voltage drop within the transformer, and the terminal voltage reduces accordingly.
[*An increase in load means more current is being drawn by that load, so an increase in load is equivalent to a decrease in load resistance]
Increase primary voltage but decraease amerage - eg double voltage and half amperage. This will double your secondary voltage. "Transformed" voltage is easy to understand by following this simple math rule. secondary voltage divided by primary voltage = no of turns on secondary and no of turns on primary. eg; 240v \ 12v = 20 (factor) this means the secondary winding is 20x the primary winding. Basically thats all I know Stick to this rule for step up & step down tranforming & you'll be sweet.
The device that increases or decreases the voltage impressed across a power line is known as a voltage regulator. A voltage regulator is a type of transformer where the primary and secondary turns ratio are fairly close; one (primary or secondary) often has a tap changing ability to add or remove several windings, allowing more dynamic control of voltage.
Terminal voltage is the voltage gotten at the terminals of the load in any system.
Voltage on primary/Primary turns = Voltage on secondary/Secondary turns
Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit." <<>> if resistor exists, resistance decreases according to ohm's law, current is directly proportional to voltage and current is inversely proportional to resistance it means as current increases, voltage increases. resistance increases, current decreases so as voltage if there is no resistor, there should be no resistance except internal resistance of voltmeter and ammeter
The generator terminal voltage will increase.
When the generator is loaded, flux per pole is reduced due to armature reaction.
Nothing, but the current will increase.

due to decrease in power factor
it decreases the high input voltage of its primary winding to a voltage level on secondary winding suitable for usage
Ohm's Law Voltage = Current x Resistance. So for a fixed voltage as R decreases then current increases proportionally.
In a transformer, you increase or decrease the voltage by changing the turns ratio between the primary or secondary windings. Increase the turns on primary, and secondary voltage goes down. Increase the turns on secondary, and secondary voltage goes up. Note that this usually involves choosing a different transformer, as changing the turns ratio is not something that can be easily done in the field. Some transformers have multiple taps on one of the windings which can be used to change turns ratio.
