Volts isn't power. Volts times amps is power, also known as watts. Thus 480 volts at 2 amps consumes 960 watts, which is the same power usage of 240 volts at 4 amps or 120 volts at 8 Amps.

Voltage itself does not consume power; rather, power consumption is determined by the combination of voltage and current. If the power demand remains the same, a higher voltage system like 480 volts will require less current to deliver the same amount of power compared to a 240-volt system. So, in general, a 480-volt system would be more efficient in terms of power transmission compared to a 240-volt system.

How many watts does 20 amps at 240 volts produce?
The unit of power is expressed in watts, and the product of current (Amps) and voltage (volts) is power there fore if you multiply the amps and the volts give watts. so 20 x 240 will give you a 4800 watts of power.
How do you modify 240 volt appliances to run directly on 12 volts?
Modifying a 240 volt appliance to run on 12 volts is not recommended due to significant differences in voltage requirements and power consumption. The appliance would likely require a complete overhaul of its internal components, which can be complex and potentially unsafe. It is safer and more efficient to use a power inverter to convert 12 volts to 240 volts for the appliance.
How many watts is 7 amps at 240 v?
To calculate power in watts, you multiply the current in amps by the voltage in volts. So, 7 amps at 240 volts would be 1680 watts (7 amps * 240 volts = 1680 watts).
How any amps in 65 Watts 240 power supply?
To calculate the current (in amps), you can use the formula: Current (Amps) = Power (Watts) / Voltage (Volts). In this case, if you have a 65-watt power supply with a voltage of 240 volts, the current would be 0.27 amps.
How many watts in 10 amps 240 volts supply?
The power can be calculated using the formula P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. Plugging in 240 volts and 10 amps, the power would be 2400 watts.

How many watts in 10 amps 240 volts supply?
The power can be calculated using the formula P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. Plugging in 240 volts and 10 amps, the power would be 2400 watts.
How 12 volts from a battery converted to 240 volts?
You will need to purchase a power inverter. Click the link for one I found.
How much current must flow to carry 240 watts at 120 volts?
240 watts at 120 volts requires 2 amperes. Power = voltage * current
If you have an 8 ohm element that operates at 240 volts uses how much power?
Power dissipated = E2/R = (240)2/8 = 7,200 watts
How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?
Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps
A hot-water heater has an 8-ohm element that operates at 240 V The power that's consumed by this water heater is?
VOLTS x (VOLTS/OHMS) = WATTS 240 X (240/8) = 7200 Watts = 7.2KWatts
What is the household AC electrical power mains socket in Eire?
