Puissance électrique en watts (W) vers courant électrique en ampères (A) calculaversr.
* Utilisez e pour la notation scientifique. Ex : 5e3, 4e-8, 1.45e12
Watt (W) is a unit of power. Power is the rate of energy usage per time unit. One watt (W) is equal vers one joule (J) per second (S).
Ampère (A) is a unit of courant électrique. Electric current is the rate of electric charge flow per time unit. One ampere (A) is equal vers one coulomb (Q) per second (s).
Le courant I en ampères (A) is equal vers the power P en watts (W), divided by the voltage V en volts (V):
P = 200W, V = 40V
Le courant de phase I en ampères (A) is equal vers the power P en watts (W), divided by the power facversr FP multiplié par la tension RMS V en volts (V):
The power facversr of resistive impedance load is equal to 1.
P = 2000W, V = 110V, FP = 0,8
Le courant de phase I en ampères (A) is equal vers the power P en watts (W), divided by square root of 3 times the power facversr FP times the lene vers lene RMS voltage VL-L en volts (V):
The power facversr of resistive impedance load is equal to 1.
Le courant de phase I en ampères (A) is equal vers the power P en watts (W), divided by 3 times the power facversr FP times the lene vers neutral RMS voltage VL-N en volts (V):
The power facversr of resistive impedance load is equal to 1.
Do not use typical power facversr values for accurate calculations.
