If it is AC voltages you need to convert, you need to find a transformer to do this job. Without knowing the application it is hard to guess what you are trying to do.
5000 volts
+3.3 volts +5 volts, +12 volts -12 volts, and -5 volts but -5 is rare
To convert watts to amps, you can use the formula: Amps = Watts / Volts. In this case, to convert 200 watts at 12 volts to amps, it would be: 200 watts / 12 volts = 16.67 amps. So, 200 watts at 12 volts is approximately 16.67 amps.
Volts cannot be converted to amps. If you mean convert 220v to 12 volts output, then you need a 220v to 12 v step down transformer with the VA or watt rating you require.
To calculate the amperage at 12 volts based on 1.5 amps at 5 volts, you can use the formula P=IV (Power = Current x Voltage). First, find the power at 5 volts (P=1.5A * 5V = 7.5 watts). Then, using P=IV at 12 volts, solve for current (7.5W = I * 12V => I = 0.625A). So, at 12 volts, 1.5 amps at 5 volts translates to approximately 0.625 amps.
To convert electron volts (eV) to centimeters (cm), you can use the formula: 1 eV 1.97 x 10-5 cm.
No, a 220 volts AC fan cannot run directly from a 12 volts battery. The fan requires a much higher voltage to operate efficiently. You would need a power inverter to convert the 12 volts from the battery to 220 volts AC to power the fan.
The product would be VA.
To what?
12 volts with the engine off. 13.5 to 15-5 volts with the engine idling.
2 volts, 5 volts, 12 volts. New computers need even less voltage.
If it is AC then you don't need a formula, you just need a transformer.
