There is no conversion. They measure different things. It's like asking 120 miles equals how many pounds?
Voltage is also called electric potential. In a water analogy it's like pressure.
Amperage is also called electric current. In a water analogy it's like flow rate.
A 1 horsepower motor typically draws around 10 amps at 120 volts and 5 amps at 240 volts. The actual amperage can vary depending on the efficiency and design of the motor.
A 60 watt light bulb typically draws 0.5 amps from a 120-volt power source. This is calculated by dividing the wattage (60 watts) by the voltage (120 volts).
On this calculation I am assuming that the light bulb is using a 120 volt source. Watts = Amps x Volts. Amps = Watts/Volts, 40/120 = .33 amps. R = Volts/Amps, 120/.33 = 363.6 ohms resistance in the 40 watt light bulb.
Watts = Amps x Volts, so 600 W / 240 V = 2.5 A 600 W / 120 V = 5 A 600 W rated balast is more like 660 W in realty, so to be safe, plan for 3A pulled per ballast. P.S. New digital balasts are much closer to 600 W, something in 610 - 620 W range.
Ohm's law states that you could calculate the current (Amp), resistance (Ohm), or voltage (Volt) as long as you know the other two. Watts is not part of this law. Therefore, your question does not give enough information.
160 amps at 12v.
160 amps at 12v.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
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 divided by volts equals amps so 6000 divided by 120 = 50
The formula you are looking for is I = W/E. 1080/120 = 9 amps. Less than 1. 1080/120 < 1
To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
1000 watts at 9.5AMPS in 120 volt = 4.7 AMPS in 240 volt ..........Divide that by 2 according to the choice of voltage... 500 watts (120V) + 4.7Amp
5.8 amps
That depends on the voltage, but the residential standard is 240 volt. At that voltage you sit at around 15 amps, however it MUST be on a 20 amp circuit for national (US) or Canadian electrical code, as you can only load your circuit to 80% of it's capacity.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
W = Amps times Volts. A = W/V, A = 300/120 = 2.5 amps
