Can you use 240 volts with a 120 volt supply?

No, it is not possible to use 240 volts with a 120 volt supply directly. You would need a transformer to step up the voltage from 120 volts to 240 volts. Attempting to use 240 volts with a 120 volt supply without a transformer can damage equipment and pose a safety hazard.

How can I convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter?

To convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter, simply plug the adapter into the 240 volt outlet and then plug your 120 volt device into the adapter. The adapter will step down the voltage from 240 volts to 120 volts, allowing you to safely power your device. Make sure the adapter is rated for the appropriate wattage to avoid damaging your device.

500 watts at 120 volts equals how many amps?

1000 watts at 9.5AMPS in 120 volt = 4.7 AMPS in 240 volt ..........Divide that by 2 according to the choice of voltage... 500 watts (120V) + 4.7Amp


If a battery has 100 amp hours at 12 volts dc how many amp hours will it have with a 120 volt ac inverter connected?

The amp hours capacity of a battery remains the same whether it is connected to a 12-volt DC load or a 120-volt AC inverter. So, the battery would still have 100 amp hours regardless of the inverter voltage.


Can i run a 240 volt water heater on 120 volt?

No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.


What size breaker for a 1500 watt 120 volt heater?

To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
