You wouldn't change these voltages in a car. Please be more specific.
depends on voltage.... 120volt = 8.33 amps , 240volt = 4.17 amps
Your neutral May not be grounded good
NO. Don't try it. Some are designed to work on either, some aren't. If it won't work on 120v, it won't work on 240v.
120volt
yes
no
1200
2400 watts.
power supply
If the capacitor is charged then the battery will explode.
it's 240volt, 50Hz. Hope that helps!
The formula you are looking for is volts x amps divided by 1000.
