Step down transformer, potentiometer or rheostats can all be used to reduce voltage.
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.
the voltage at which electronic device operates is callled threshold voltageand the voltage at which device show cinduction in forward biased stste
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.
the voltage above which any device starts conducting
A transformer can perform this function.
A transformer can step up or step down AC voltage
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to Transformers to provide customers with a regulated voltage at the desired voltage.

Ohm's law: I=E/R I=Current, E=Voltage, R=Resistance. If E decreases and R remains the same, I decreases.
A rectifier is an electronic device that changes an AC voltage to a DC voltage.

the device oprates on the minimum voltage. in this voltage is called threshold voltage.
