Whats the difference between amps and watts??

  • Answer:

    Amps are the unit of current flow. (Analogy: where water flows through a pipe, litres per second.) Watts are the unit of power, i.e. how much work a device can do. (Analogy: Horsepower in a car.) Watts are not confined to electrical devices. The power of anything can be measured in watts. My car is quoted in the handbook as 160,000 watts, or 160kw. And electrical devices can be measured in horsepower, though it's unusual.

Amperes are a measure of current. Watts are measures of power. Watts are amps times volts.

Amperes are measurements of current. Watts are a measurement of power. Watts = Amps * Volts.

Amperage ("amps"), is the amount of electric current per second, flowing past a given point in a electric circuit. Watts is a measure of energy flow per second. If the same amount of electric current is flowing past 2 points, and if there is a voltage difference between these points, then: ... Watts = amps x volts.

Consider a circuit in which there is a voltage supply,V say. The circuit consists of a resistor R, ohms. When the circuit is completed a current will flow through the resistor and the current is usually referred to as I. Example let V = 240 volts and R = 40 ohms The current is given by 240/40 amps = 6A Power taken by resistor is given by VI or I²R and is measured in watts, W Check: V x I = 240 x 6 W = 1440 W = 1.44 kW and I² R = 6² x 40 W = 36 x 40W = 1440W = 1.44 kW

Amps measure current, watts measure power.

Amps is the standard unit of measurement for electrical current. Watts is the standard unit of measurement for power.

Watt = Puissance=travail/temps Joule = energie=travail Watt*h=travail Amper= Coulomb / temps

Not Ecky boy is right. The difference is purely a measurement. There are Volts (Electric pressure), Amps (current or flow of electrons) and Resistance (load measured in ohms) You can have the same wattage but entirely different voltages and amperage. For instance, you can have 10 volts and 1 amp which equals (10 X 1) 10 Watts, or you could have 5 volts and 2 amps, again = 10 watts, or even 1 volt and 10 amps. Wattage is a more convenient way of measuring the useful energy being used or delivered. There is a cross reference between wattage and horsepower, but it's been a long time since I studied these numbers. Ohms Law states that (V)oltage is equal to (A)mps times (O)hms (E = I x R) I = E / R R = E / I

Amps are the measure of current - ie. rate of transfer of power. Watts are the measure of power, ie. an absolute.
