If you are dealing with AC voltage, you can use a transformer. You can find Transformers at places like Radio Shack, Jaycar and some online sites like eBay. Transformers have to be connected in the right way. You have to connect the voltage you are going to increase to the low voltage side and on the high voltage side will be the voltage which has been stepped up by the transformer. (If you want a DC voltage out, you will need to connect a bridge rectifier to the output, followed by a large capacitor and then a voltage regulator of the voltage you want out.)
If you are dealing with DC voltage then you will need a chip to step the voltage up. These chips can step voltage up from around 1 to 10 volts to at least 20 to 30 volts. These chips also need to be connected correctly. You will need more components than using a transformer. You will probably need some capacitors and some resistors. Depending on the IC you choose, you will find many circuits on Google for it and how to build them.
By far the easiest type of voltage to step up is AC. If you have the option of AC, and need to have a very high voltage output, you are better off using a transformer, bridge rectifier and a rectifier.
What else can I help you with?
What would be the effect of increasing the voltage of the battery?
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
Does voltage increase in parallel?
yes
What is the fuction of the step-up transformer?
Step-Up Transformers increase the primary voltage to a higher voltage, of same frequency.
As the voltage applied to a circuit increases the current and the also increase?
answer is actually voltage
Will the power consumed by an electrical appliance increase with a reduction of applied voltage?
Power consumed by an electrical appliance will increase with a reduction of applied voltage.
What is the effect of surge arrester on increase the voltage in medium voltage circuits?
What is the effect of surge arrested on increase the voltage in medium voltage circuits?
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
Will the resistors ohmic value increase if you increase the voltage?
No.
Can a voltmeter increase its voltage?
no
What is the name of the component that is used to increase or decrease alternating voltage?
A transformer is used to increase or decrease alternating voltage.
What would be the effect of increasing the voltage of the battery?
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
Can a voltmeter increase voltage?
No, a voltmeter measures voltage in a circuit but cannot increase it. It is a passive device that is simply used to read the voltage at a specific point in the circuit.
When voltage increase then current will be?
it depends on what type of load. Motor amperage will drop off as voltage rises. loads such as lights will increase amperage with voltage rise.
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.
How can we increase the strength of an electro magnet?
Increase voltage. Increase the number of windings,
How do you decrease voltage?
Increase resistance
Does voltage increase in parallel?
yes
