This depends on the circuitry you apply voltage to.
In a circuitry with a fixed resistance of 1 Ohm, 1 Volt would then generate 1 Ampere of Current.
In the same circuitry, 2 Volt would generate 2 Ampere of Current.
Increased voltage will, given the same circumstances, increase the current.
In other words, your question must take something not defined into consideration, or the question may be wrong.
In an attempt to explain why it often works this way I have to look away from fixed circuitries and give real life examples.
By increasing the voltage, the effect of the resistance in an electrical cable is lowered.
In other words, a thinner cable can carry the same "juice" of 360 Volt as compared with a thicker cable of 220 Volt or an even thicker one running at only 120 Volt.
This makes much sense in the fact that thinner cables are cheaper. In a big house, there is much to gain by having access to higher voltages.
A washingmachine, stove, cooker, tumbledryer, dishwasher... All can be made to utilize high voltage instead of low voltage. The current drained goes down, but the wattage remain the same.
The electricity company benefit from less effect of resistance in the cables. They can give more punch with less.
We can also look at a fixed wattage.
If the wattage drained remains the same no matter the voltage, then the current goes down as the voltage rises.

Can ac pass through capacitor?
AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.
What size circuit breaker should be used if you use 5 horsepower of air-conditioning?
To answer this question a voltage value must be given. Circuit breakers protect the conductors that feed the load. The lower the voltage value, the higher the current value, hence a larger the wire size is needed and therefore larger the breaker size for the circuit. In reverse the higher the voltage value, the lower the current value, hence a smaller the wire size can be used therefore smaller the breaker size for the circuit.
What is the breakdown voltage of PN junction diode?
A Zener diode doesn't allow almost any current to flow below a certain voltage. Above this voltage (the breakdown voltage), the amount of current that can flow is almost unlimited; meaning that the device acts as an "open" for lower voltages, and as a "short" for higher voltages.
What unit measures the force that makes electrons move in an electric current?
The force that makes electrons move is a voltage, or potential difference and both are measured in Volts. When electrons move, the rate of movement is current, measured in Amps. The amount of current is dependant on both the resistance in a circuit and the voltage. The higher the resistance, the lower the current. The higher the voltage, the greater the current. The symbol for voltage is "V" and confusingly, the symbol for current is "I". The unit of resistance is the Ohm with the symbol "R" or the Greek symbol for omega.
What can't we use step-up transformer to increase the voltage by producing electricity of lower voltage?
This question is not understandable. You can use a step up transformer to increase voltage; you can't increase voltage by producing electricity at a lower voltage; this will result in current flow into your generator, not current flow out (similar to operating a generator in the leading mode). Please explain further under "discuss question".
Electrons flow from areas of higher to lower voltage or from areas of lower to higher voltage?
Electronsflow from areas of lower to higher voltage, while Current flow from areas higher to lower voltage.
When a circuit is inductive the current has what voltage?
This doesn't make sense, "current" is "amperage" so the higher the voltage the lower the amperage, and the lower the voltage the higher the amperage.
Is it true that electrical current flows from a state of rest to a high pressure state?
No, it is not true. An electrical current (which is a flow of electrons) can only flow from a higher pressure state (higher voltage) to a lower pressure state (lower voltage).
Is the resistance lower if you have a high current?
Lower than what? For the same voltage, a lower resistance means higher current. But beware, the voltage itself might depend on the current - thus - with a fixed resistance if you change the voltage, you will increase the current in the same proportion. Some things become higher resistance if they get hot (a tungsten filament in a lamp). Other things become lower resistance if they get hot (semiconductors). So it can all depend on what kind of circuit you have.
What is buck boost converter?
Any device that outputs a voltage higher than its input voltage. This device can be capacitive, inductive, or other.
Does a step-down transformer increase its voltage and and decrease it's current?
No. A step-down transformer's secondary voltage is lower than its primary voltage. The secondary current is determined by the load, and this causes a higher current in the primary winding.
When testing a power transformer with an ohmmeter which winding should have the largest ohmic value?
The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
Will lower DC voltage or higher DC voltage burn out switch contacts faster if current and resistance stay the same?
if there is resistance in the contact surface , it would heat up more with higher voltage .
Why are the readings on a ammeter always different?
The readings on an ammeter indicate the current being drawn by a load in a circuit. This load is basically a resistance to current flow. The higher the resistance, the lower the current. The supply voltage has a direct effect on current flow. The higher the voltage applied, the higher the current will be. So the readings will vary on the ammeter according to fluctuations in load and or resistance of the circuit and the applied voltage.
Is there more current in the primary or secondary winding of a transformer?
The terms, 'primary' and 'secondary', describe how a transformer is connected and his nothing to do with which is the lower- and higher-voltage winding.The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. So, for astep-up transformer, the secondary winding is the higher voltage winding, whereas for a step-down transformer, the secondary winding is the lower voltage winding.For a loaded transformer, i.e. a transformer whose secondary is supplying a load, the higher-voltage winding carries the smaller current, while the lower-voltage winding carries the higher current.
What happens inside a voltmeter when you switch it from a lower to a higher voltage range?
When you switch a voltmeter from a lower to a higher voltage range, an additional resistor is added in series with the meter, increasing the voltage necessary to create the same voltage drop across or current flow through the actual meter movement.
HOw does electricity get transported and why does it need to be at a high voltage?
The primary reason that power is transmitted at high voltages is to increase efficiency. ... The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.
