In that case, the current will also be doubled. This follows from Ohm's Law (current = voltage / resitance)

Is current the voltage multiplied by resistance?
No. V =Voltage, I =current, and R =resistancein the simple equation: V=I*R. As well, V/I=R, and. V/R=Iso Current is voltage divided by resistance
Amps times ohms equal?
voltage! measured in volts. current X resistance = voltage simple ohms law
What does it mean to say that current and voltage in a circuit are directly related?
It means that when one increases, the other increases as well. Also, it implies that this increase is proportional - if the voltage is doubled, the current will also double. Note 1: Normally, the voltage is considered the independent quantity; that's the quantity you can control directly. And if the voltage changes, so will the current. Note 2: In simple circuits, such as those that only have a voltage source and resistors, the relation will be a direct proportion. With electronic components, such as a transistor, the relationships can be more complicated.
Why does the current rise when the voltage drops?
It is not generally true that current increases when the voltage decreases. Ohms law for a simple resistor says that current is proportional to voltage. However an electric motor supplying a constant mechanical load power will readjust to a lower supply voltage by drawing more current, although if the voltage is progressively reduced the motor would stall. Switch-mode power supplies also tend to draw a constant power from the supply when the input voltage changes.
How do you transform transformers?
Open the equipment, unsolder the connections to the transformer, remove the fastenings and remove it. Order a new on on ebay, when it arrives unpack it carefully, place it in the equipment, fasten it in, and resolder the connections. Simple! - (Historikeren 13-07-2014)
How does the potential difference across the electric circuit affect current?
In a very simple way. As long as nothing changes in the circuit, the current that flows from the power supply or battery into the circuit is directly proportional to the voltage of the supply. -- If you double the voltage across the ends of the circuit, the current will double. -- If you turn the voltage up to 3.4027 times its original value, the current will increase to 3.4027 times its original value. -- If you decrease the voltage by 81.7 percent, the current will decrease by 81.7 percent.
What does electric current do for us?
If the question means "What does electricity do for us?" then we could mention lighting, heating, cookers, refrigerators, telephones and cellphones, radios, TVs, computers for a simple start. If the question seeks to differentiate between electric voltage and electric current, then voltage is the measure of the energy of an electric charge and current is a measure of the flow of the charge.
What is a electrical curcuit?
An electric circuit is a path in which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. Its so simple, though my friend from extraminds help me with proper answer.
Certain electric devices such as cordless telephones have small transformers that plug into walls.what do the transformers do?
Transformers are relatively simple devices which change both the current and the voltage of an electric source without affecting the total amount of power being given. Power, as the product of current and voltage, is mostly conserved as transformers are used, but the current and voltage changes. If the device needs just half the voltage of what is coming out of your wall (240v in Australia), then it will 'step down' this voltage by half, but will have to 'step up' the current, so your voltage will halve, your current will double, but the total amount of power will remain the same. Essentially the transformer exists to give your device the required input of electricity so your device is not fried!
How can you increase or double electric power output electronically?
A: Well that is not possible. Someone can change the voltage up or down with no problem but never can it increase power by adding any kind of circuitry for the simple fact of % efficiency loss. If it could be possible then we have infinite power source available.
How many watts does an electric drill use?
To figure that out you need to know the Amperage that it draws and what the voltage of the circuit is that you're using. Once you know that you can figure out how many watts it uses by doing simple math. Voltage x Amperage = Watts

Why an electric connection has 2 wires?
Two wires are needed so that the electric current has a circuit to flow round. For a simple circuit, the voltage between the wires, multiplied by the current in amps, gives the power in watts, which is how fast energy is used up (joules per second). Also, the voltage divided by the current gives the resistance of the load, in Ohms.
How can you increase voltage of an ac adapter?
Increase primary voltage but decraease amerage - eg double voltage and half amperage. This will double your secondary voltage. "Transformed" voltage is easy to understand by following this simple math rule. secondary voltage divided by primary voltage = no of turns on secondary and no of turns on primary. eg; 240v \ 12v = 20 (factor) this means the secondary winding is 20x the primary winding. Basically thats all I know Stick to this rule for step up & step down tranforming & you'll be sweet.
What electric inventions could found in cities?
That is simple. Electric signs,electric light bulbs,and electric streetcars
What are two things required to make electric current flow in a circuit?
you need an electrical supply and a load. nice and simple.
