Amperage is the measure of electrical current, which is the measure of the electron flow through something (like a wire). The more electrons that flow through the wire, the higher the amperage. Current is understood as moving from higher voltage to lower voltage but since electrons are negatively charged, they actually flow in the opposite direction.
Voltage is a measure of electrical potential between two items. The electrical potential can be looked at as the difference in the electrical charge between two items. The item with more negatively charged electrons has a lower voltage.

∙ 8y agoCurrent describes the movement of charge carriers through a material (free electrons, in the case of a metal conductor). Current is measured in amperes (A), which is defined in terms of the force between two, parallel, current-carrying conductors, due to the magnetic fields around those conductors.
Voltage is synonymous with potential difference, which describes the 'driving force' necessary for current flow within a circuit. Potential difference is measured in volts(V), which is defined in terms of the amount of energy necessary to transport a given quantity of charge between two points in a circuit.

What is a volt-ampere the product of?
A volt - ampere is the unit for the product of voltage and current. This is power. Power = voltage x current. The unit of power is more usually called the watt. Volts x amps = watts.
How do you calculate voltage's ampere's resistances in dc automobile systems?
Ohm's Law applies where Voltage = Current x Resistance
In a light circuit with a constant voltage what is the effect on the current if the light bulb is doubled?
If you add one extra bulb and the voltage remains constant, then you have doubled the current drained from the regulator. 12 Volt and One 12 Watt lightbulb drains 1 Ampere Current. 12 Volt and Two 12 Watt light bulbs drains 2 Ampere Current. However: If having a 24 volt powersource and you add two 12 Volt 12 Watt in serial, then you still only drain 1 Ampere Current. NOTE: Wattage and Voltage of bulbs may be different even if the sockets are the same. Lower voltage on the bulb will increase the current drain, if voltage is a lot lower it might cause the circuit delivering voltage to burn out or blow a fuse. It can also quickly burn the bulb, sometimes in a fraction of a second. It will however do little damage to add a bulb with higher voltage than the circuit is designed for. You will then only observe that you do not get the light you might hope for. Total Current/Ampere= Combined Wattage divided by Voltage Total Wattage = Combined Current or Ampere multiplied by Voltage. Regards.
What is the result of 230VAC divided by 30 ohms?

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)
List the units for measuring current and voltage?
The unit of voltage is the "volt". The unit of current, sometimes called "amperage", is the "ampere".
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.

Is 0.01 Milli ampere is dangerous?
How high is the voltage that is being used? With high enough voltage any current is dangerous.
A trouble light has a resistance of 12 ohms and is rated 1 2 ampere what voltage must be applied to obtain the rates current?
I'm not entirely sure what your question is.if the current is 12 ampere's, the voltage is 144 voltsif the current is 1.2 amperes, the voltage is 14.4 voltsSimple multiplication....................
If the resistance of an electric current is 12 ohms and the voltage in the current is 60 V the current flowing through the circuit is?
..using the formula Voltage(V)=Current(I) * Resistance(R) .. we can get the result ...current will be 5 Ampere
