Can you reduce amperage by using thicker wire with a constant voltage?

The amperage flowing through a wire is directly related to the load placed on the circuit, and has nothing to do with wire size, except that a larger wire will carry more amperage. Increasing wire size will not lower amperage but will allow the circuit to carry more amperage if the breaker is also increased in size.
No. Ohm's law tells us that V = IR. For a given load, R is constant, and thus the only way to reduce current is to increase voltage.

What are the problems one can expect with low supply voltage or fluctuations in split AC?
depends on how low incoming ppower is unit will have min max allowable voltage on name plate but the lower the voltage the higher the amperage draw which can reduce life of compressor or even kill it
If a resistor decreases in value what will happen to the current through the resistor?
If the voltage applied across the resistor remains constant, then as the resistance of the resistor decreases, the current through it will increase. Consider Ohm's Law: E = IR In this formula, in order for 'E' to remain constant as 'R' decreases, 'I' must increase. Another form of Ohm's Law: I = E/R If 'E' remains constant, then the value of the fraction increases as its denominator 'R' decreases.
A device that decreases voltage?
Step down transformer, potentiometer or rheostats can all be used to reduce voltage.
What is a voltage droop used for?
The purpose of a voltage droop is to intentionally reduce the voltage of a device. Further information about why and when one would do this can be found on Wikipedia.
The voltage drop in line can be decreased by?
The voltage drop in a line can be decreased by
When voltage increases what happens to the amps?
the power will also increase as it is proved in my experiment

The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
Can using larger wire sizes reduce amp draw?
Larger wires will not reduce the amperage draw of a device. Limiting amperage draw is accomplished by fuses wich blow when the amperage drawn across them exceeds their specifications.
What happens if the current is constant and voltage increases?
Generally the voltage is constant and current varies as per the load. Load can vary and hence current can vary. You are stating an abnormal situation, where in voltage increases while current remains constant. I am assuming a constant load situation then normally when voltage increases, the current tends to reduce since over all load remains same. If the voltage goes up beyond a limit the insulation fails and may lead to short circuit, equipment failure, shock and fatality
How do you increase voltage?
You can put less resistance (more load) on the battery with larger wires, but if you exceed a particular current output for a given duration, you will overheat the battery. To safely increase current output, use two batteries connected in parallel.
Why is electricity transported at low amperage?
To reduce power loss in the cable.
Reducing the current you a circuit causes what?
Reducing the current to a circuit causes a higher resistance -- assuming constant Volts. Also, reducing the current to a circuit causes lower Volts -- assuming constant resistance.AnswerAltering the current has absolutely no effect on a circuit's resistance. Reducing the current will reduce line losses (I2R) and reduce the voltage drop along a conductor.
How must the voltage across a resistor change to reduce the current in the resistor by a factor of 3?
The voltage must reduce by the same factor - that is Ohm's law.
What does it means to reduce by or reduce to?
In cooking terminology, that is generally referring to cooking a liquid down - making it thicker and richer in flavor.
If a resistor decreases in value what will happen to the current through the resistor?
If the voltage applied across the resistor remains constant, then as the resistance of the resistor decreases, the current through it will increase. Consider Ohm's Law: E = IR In this formula, in order for 'E' to remain constant as 'R' decreases, 'I' must increase. Another form of Ohm's Law: I = E/R If 'E' remains constant, then the value of the fraction increases as its denominator 'R' decreases.
Why is the voltage stepped up before transmission?
Voltage is stepped up during transmission to reduce the power loss during transmission due to resistance. Power is a product of Voltage*Current, and losses due to resistance are directly proportional to the square of the current. Now when we increase the voltage , keeping the power constant, the subsequent current reduces.. thus in turn reducing the transmission losses.
