There is a way to use capacitors to increase the voltage in an ac circuit. It increases it by about 50 %. It was used to increase the voltage going to motors. It is seldom used now that it is much easier to run a higher voltage line into a place of business. It does not work for Direct Current.

∙ 10y agoHigher voltage means a bigger current flow. And with both more voltage and more current the circuit will also be making more power. And more power usually means more heat.

What is added to a circuit to make the current smaller?
The reduction of voltage or the increase of resistance will reduce the current in a circuit.
Is there any way to increase the amount of power that can pass through a circuit without it over heating?
increase voltage
When speed of fan is increase what is effect on voltage?
voltage would go up typically (you would raise the voltage, not the fan circuit), but it depends on the motor
Does miliamperes increase as does battery voltage when put in a series configuration?
The current in a circuit, expressed in milliamperes, is1,000 x (battery or power supply voltage)/(resistance connected between the power supply terminals)If you increase the voltage of the battery or power supply, the current in the circuitincreases proportionally, at least until something in the circuit gets hot, melts, fuses,and opens the circuit.
If voltage changes in a ac circuit what happens to current?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
What happens in a circuit if you increase the voltage of the battery driving it?
The power in the circuit will increase.
Is the increase in voltage causes a greater electric resistance in a circuit?
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
What does an increase in voltage cause in an electric circuit?
It causes a proportional increase in current.
Describe two ways to increase the current in a circuit?
1. Increase the voltage while holding the resistance constant.and2. Decreasing the resistance while holding the voltage constant.For a fixed load, increase the supply voltage. For a fixed supply voltage, increase the load.So that there is no confusion, 'increasing a load' means reducing the resistance (in the case of a d.c. circuit) or reducing the impedance (in the case of an a.c. circuit).
Can you increase current in a circuit without change in resistance and voltage?
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
As the voltage applied to a circuit increases the current and the also increase?
answer is actually voltage
When electric current is flowing in a circuit if the voltage applied to the circuit is increased the?
Correct Answer= "the current will increase"
What can you increase by using more cells in a science circuit?
more voltage
How must batteries be connected in order to increase the voltage in a circuit?
in series
What would increase if the voltage in a circuit is increased?
The powerBrightness of the bulbThe current
Will current increase if the voltage in a circuit is increased?
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.
