240 volts
208 to 240 volts depending on your local power supply.
2 volts
25,000 volts
14 volts
Usually 220 to 240 VAC.
300 i think
650
about 450V to 600V
To determine the amperage of a 400-watt solar panel, you can use the formula: Amps = Watts / Volts. Assuming the panel operates at a nominal voltage of 24 volts, it would produce approximately 16.67 amps (400 watts / 24 volts). If the panel operates at 12 volts, it would produce about 33.33 amps (400 watts / 12 volts). The actual output can vary based on factors like sunlight intensity and panel efficiency.
I assume you are referring to a residential electric panel. The amount of amps has nothing to do with the voltage. They are independent. A typical residential electric panel will have 120 V. That is the easy answer. Usually there are two hot feeds with 120 V to ground. Between the two hot feeds will be 240 V. The bus bars are arranged in the panel so that when you plug in breakers they alternate between the feeds.
Usually 2,000 to 2,200 volts at 7 to 12 amps.
