480 volts is probably 3-phase (Line to line) voltage, so:
1500K / (480 x 1.732) = I = 1804Amps
Volts times amps equals watts, so watts divided by volts equals amps, so 15 amps
Ohm's Law: Voltage = Amperes times Resistance 9 volts = amps * 10 ohms amps = .9
Ohm's Law.
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps
4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.
Watts is volts times amps, so 12 x 30 = 360 watts
160 amps at 12v.
160 amps at 12v.
23.6 amps
On a 1kva you have 1000 watts capacity. To fine the current the formula is I = W/E. The secondary side of the transformer has the capacity of 1000/120 = 8.3 amps. In your question you do not put the amps across the secondary you draw amps from it. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. <<>> voltage times amps equals wattage
Rephrase your question, as it doesn't make any sense. If the primary side of the transformer is 480 volts 3 phase, this transformer can be supplied from a breaker as big as 180 amps. If 480 volts 3 phase is your secondary then you can supply up to 180 amps to your loads.
2.083 amps
Watts are amps x volts, so w/o the volts the question can't be answered. At 100 volts it'd be 15 amps.
450 watts divided by 120 volts equals 3.75 amps450 watts divided by 12 volts equals 37.5 ampswatts divided by volts equals amps
Watts is a power level, not a voltage. The wattage in a circuit is defined as Volts x Amps, so you need to know the current before you can work out the voltage.
It's watts divided by volts equals amps. Example: 1200 watts at 120 volts is 10 amps. To get the watts if you know the amps, multiply the amps times the volts. 10 amps at 120 volts is 1200 watts.
Watts=Volts times Amps So without knowing the voltage the amps can be anything. At 100 Volts it'd be 14 Amps.
