How many amperes are 500KVA and 380V? How to calculate? Is there a formula? I can't understand other answers
I=S÷(√3×U)=500000÷(√3×380)=760A
How many amperes is 1.8 kilowatt?
My water pump is 1.8kw. I want to install a time controller, but it can't exceed 15A. I want to know
If the voltage is 220 V, the current of 1 A is 1 x220 = 220 w = 0.22 kW
So 1.8 kW is about 1.8/0.22 = 8.18a
If your water pump is used under the voltage of 220 V, there should be no problem,
How much energy is consumed in 5 minutes when a household electrical appliance marked with "220 V 2A" is connected to the home circuit?
I just came into contact with electric power. Alas, it's a mess. I hope you can help me
P=UI
=220*2
=440W
W=Pt
=440*300
=132000J
When a bulb is connected to a circuit with a voltage of 220 V, the current passing through the bulb is 0.5 A and the power on time is 1 h, how much electric energy does it consume?
W=UIt=220*0.5*1*3600=396000J .
