Ampere (A) is a unit of electric current. Electric current is the rate of electric charge flow per time unit. One ampere (A) is equal to one coulomb (Q) per second (s). DC watts to amps calculation. The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V): I(A) = P(W) V(V) Example. P = 200W, V = 40V. I =
The formula for converting watts to amps is: Amps = Watts ÷ Volts. How to convert watts to amps. To convert watts (electrical power) to amps (electrical current) at a fixed voltage, you can use a variation of Watt's Law formula: Power = Current × Voltage (P = IV).
Convert watts to amps for DC and single or three-phase AC circuits, plus learn several formulas for watt to amp electrical conversions.
To convert amps (electrical current) to watts (electrical power) at a fixed voltage, you can use the equation: watts = amps × volts. Simply multiply your amps figure by the voltage. Example calculations. 15 amps × 120 volts = 1800 watts; 20 amps × 120 volts = 2400 watts
This watts to amps calculator helps to convert electrical power (watts) to electrical current (amps) for resolving electrical issues and maintaining safety.
Multiply the battery's voltage by its amp-hours to get the battery's capacity in Watt-hours: capacity (in Wh) = voltage × amp-hours. Discover the relationship between power, voltage, current, and resistance with our intuitive watt calculator.
The watts-to-amps calculator helps you convert the electric power into amperage, or vice versa, depending on the current type.
