You can have a circuit that draws 500 amps at 10 volts (500 * 10 = 5000 watts). Or you can have a circuit that draws 10 amps at 500 volts. Or maybe even 100 amps at 50 volts. These all provide 5,000 watts of power, but all have different currents and voltages.
You can have a circuit that consumes 500 amps at 10 volts (500 * 10 = 5000 watts). Or you can have a circuit that draws 10 amps at 500 volts.
Watts and amps corresponding to 120V ACCurrent voltage
|50 watts||0.4167 amps||120 volts|
|100 watts||0.8333 amps||120 volts|
|150 watts||1. ### 25 amps||120 volts|
|200 watts||1,667 amps||120 volts|
A 5000 watt generator can power a lamp, fan, radio, television, water pump, hair dryer, portable electric heater, and electric blanket. The generator can power any small device with less than 5000 watts of power.
Watts = volts * amps. So if your amplifier is delivering 1000W RMS and using a 12V power supply, it will need 83 amps. There are two other factors to consider. The amplifier is not 100% efficient, so assume 50% efficiency and you have 166 amps. Since 1000W is a peak value, you can reduce it to 1/3 which will give you around 55 amps.
There is a maximum of 12 lights and / or sockets on this tour. A 1000W HPS or metal halide lamp draws 9 amps at 120 volts, so you can only use one on a wall outlet. A standard dryer outlet has 220 volts and 30 amps, so you can run up to six 1000-watt lights on this circuit.
To get 3000 watts of 120 volts AC from an inverter, it is necessary to replace the 100 AMP generator with an expensive 250 AMP generator and install PI high capacity batteries. In addition, 50 amplifiers are required for vehicle accessories, lights, indicators, etc.
For standard 120-volt operation, a 20-amp breaker can support up to 2,400 watts on a single circuit. However, the circuits need not be loaded beyond 80% of their maximum capacity for a longer period of time, which makes 1920 watts the safe maximum for a 20A circuit.
To convert volts to amperes, it is a measure of current. You can use a formula defined by Watt’s law. Watt’s law says that current = supply voltage. Power is measured in watts and voltage is measured in volts. For example, find out the power of a 100 watt, 120 volt light bulb.
Measurements of corresponding volts and watts
The formula for amplifiers is watts divided by volts. To use the graph, you need to cover A with your finger and use the remaining graph calculation of W divided by V. Using our example panel data, 60 watts divided by 12 volts equals 5 amps.
