If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
If voltage is constant, then increasing current requires that resistance decreases.
increasing resistance and keeping current constant
Power is voltage times current. If you want to maintain constant voltage and yet increase power, then current must increase. Its simple math.
You should answer this question yourself by doing a couple of examples using Ohm's law I=E/R (current equals voltage divided by resistance. Here they are: Base circuit: 10 volt supply feeding a 10 ohm resistor calculate the current... New circuit: 10 volt supply (voltage kept constant) feeding a 20 ohm resistor (increased resistance) calculate the current... Did the current increase, or decrease? This way you can prove to yourself the answer!
the current will increase because of a lower level of resistance , hence more current will flow- easily
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.

a constant resistance
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
Ohm's Law states Voltage = Current x Resistance. Hence if voltage is increased and resistance is constant, current will increase proportionally to the rise in voltage.
According to Ohm's law i.e. E=IR. When we increase resistance, keeping current constant, voltage will increase as in the above formula since E and R are directly proportional.
Current will increase
Basically we should also keep in mind knowledge about voltage and current. If we keep voltage constant then by increase in temperature also increase the attenuation, if we keep current constant then attenuation drops by increasing temperature.
Power is voltage times current. If you want to maintain constant voltage and yet increase power, then current must increase. Its simple math.
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
According to Ohms law, current will increase in proportion to the voltage increase. Ohms law is an equation:Voltage = current x resistance.If the resistance stays the same, any increase in voltage must mean a proportional increase in current according to this equation.
