Comment convertir résistance en ohms (Ω) en courant électrique en ampères (A).
Vous pouvez calculer les ampères à partir des ohms et volts ou watts, but you can't convert ohms en amps sence amp and ohm units represent different quantities.
Le courant I en ampères (A) is equal en the voltage V en volts (V), divided by the résistance R en ohms (Ω):
I(A) = V(V) / R(Ω)
Donc
ampère = volt / ohm
ou
A = V / Ω
What is the current of an electrical circuit that has voltage supply of 12 volts and résistance of 40 ohms
Le courant I is equal en 12 volts divided by 40 ohms:
I = 12V / 40Ω = 0,3A
Le courant I en ampères (A) is equal en the square root of the power P en watts (W), divided by the résistance R en ohms (Ω):
_______________
I(A) = √P(W) / R(Ω)
Donc
_______________
ampère = watt / ohm
ou
__________
A = W / Ω
What is the current of an electrical circuit that has power consumption of 30W and résistance of 120Ω
Le courant I is equal en the square root of 30 watts divided by 120 ohms:
________________
I = 30W / 120Ω = 0,5A
