What is amps measure?
Ampere is the SI unit of electric current.
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. You can relate the two if you know the Voltage. For example, if your car has a 12V battery and your stereo draws 10 Amps of current, you are using 120 Watts of power. [Power in Watts] = [Voltage in Volts] x [Current in Amps]
You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!
If you would like to measure amps, there are two ways. First, you can splice the wire you'd like to measure the amps of in half, and have the ammeter/multimeter test leads touch each of the wire's sides. Now the circuit will connect up again as if you never cut the cable, and you can measure amps. The easier way is to get a clamp meter, which has a large loop that you can clip…
Watts and amps measure different things, and they cannot be converted as asked. Watts measures power. Volts measures voltage and amps is a measure of current. The three electrical parameters are related by this formula: Power (watts) = volts times amps. If you know the voltage, then you can find the watt-to-amp ratio.
Here's something for you: http://www.akatoo.com/question.html?question_id=55474 Watts = Amps x Volts, Amps = Volts/Resistance. Measure the resistance of the bulb and divide it into the voltage the bulb uses. This will give you the amps drawn by the bulb. Now multiply the amps by the volts and it will give you the watts the bulb draws. eg. a 120 volt bulb has 144 ohms resistance, Amps = 120/144 = .833 amps. .833 amps x 120 volts…
The amps being delivered by a battery depends on what it's connected to and what job it's doing. When there's nothing connected to it, it's supplying zero amps. To measure the amps with an ordinary multimeter, the amps must flow through the meter. That means you have to disconnect one wire from the battery and temporarily wire the meter into the 'gap', so that all the current flows through it.
There really is no fixed answer. Amps are a measure of current, while watts are a measure of work. To get the answer, you need to know either how many volts you are dealing with, or how much resistance; the relationship is W= V*I (where I is the current in amps). That said, for a typical 120 volt household current, the number of watts would be 180.
Amperage (Amps) is a measure of current flow Voltage (Volts) is an electrical measure of difference in potential Wattage (Watts) is a measure of power which is energy per unit time A kilowatt equals 1000 watts Kilowatt Hour (KWH) is a measure of energy (Watts x hours/1000) The relationship is: Power (Watts) = Voltages (Volts) x Amperage (Amps) Therefore, Amps = Power (KW) x 1000 / Voltage (Volts)
