Outdoor power is becoming more and more popular, many small partners on the introduction of outdoor power products on some parameters are not very clear, today to give you a brief introduction to the outdoor power volts amperage watt-number difference;
Volt, amperage, wattage difference:
1. The physical quantities represented are different
The physical quantity represented by amperes is current intensity.
Volt represents the physical quantity is voltage, electromotive force.
The physical quantity that watt stands for is power.
2. The units of volt, amperage and wattage are different
The SI unit of amperage is A.
The SI unit of volts is V(W/A).
The English unit of wattage is W(J/s).
The role of volts, amperes and wattages:
Amperage: A constant current is passed through two parallel wires of infinite length and negligible circular section 1 meter apart in a vacuum, when the force generated between the two wires per meter length is equal to 2×10-7 Newtons.
Volts: is the potential difference between the two points when the power dissipation on the wire between the two points is 1W (1W=1 J/S) on a wire with constant current at load 1A.
Wattage: refers to 1W is the object in 1s time to do J work.
