If it is an alternating current (ac) circuit you could use suitable a step-down transformer.
If the circuit uses direct current (dc) then you could use a drop-down resistor if you know the load's current draw in amps. Then, using Ohms' Law, the value of the resistor in ohms can be calculated.
For example if the current drawn by the 12 volt load is 1 amp, you would need to "lose" 48 - 12 = 36 volts, so, using Ohm's Law (R = E / A) the resistor would need to have a resistance value of 36 / 1 = 36 ohms.
The resistor would have to be big enough to run safely without overheating, so, using the Power Law (W = E x I) its power rating would have to be at least 36 x 1 = 36 watts. That is not a trivial amount of power to dissipate - it's about the same power as a 40 watt electric light bulb - so it would be a good idea to make sure the resistor is mounted in such a way that it can lose its heat safely without burning anything.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
No, the voltage of 500 volts is too high to operate a 380 volt motor.
If a 48 Volt club car electric motor requires 48 volts, then it should be given a 48 volt power source, or something close to it. Too many more volts and it may burn out; not enough volts and it may not run or it will try to draw too much power and burn out the power supply.
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
It looks like the crucial number was left out of the question, between the words "volt ... amp DC". If the device says it needs 5 volts at 2 amp, it will run safely on any DC power supply rated at 5 volts and (2 or more) amps.
Since there is an AC to DC converter in there, it's hard to say. If it's a basic transformer to rectifier to capacitor design it will put out 6 volts. If it is a transformer to a voltage regulator it's hard to say what will happen. Certainly the drive voltage to the regularor will be cut in half. It may or may not run, but won't be able to run at 12 volts because there won't be any 12 volts to drive the regulator. (There will only be 6 volts.) If it is a switcher it may work fine or it may do nothing.
Yes, a device rated for 127 volts should operate on 110 volt power without issues. The device may run slightly slower or with slightly reduced performance due to the lower voltage, but it should work safely.
No, you will need two 12 volt batteries connected in series to give the 24 volts necessary to run the pump. It will not run on 12 volts.
There is a 3.75 Volt drop across each bulb.
No, unless the motor was wound for dual voltage operation, which it will state on the motor nameplate, a 110 volt motor run on 240 volts will be damaged.
Yes. However, the device me not run at its optimum capacity/speed. Other thing to take into consideration is that the polarity (+/-) of adapter and the receiving device must match.
yes, but it may burn out
It is not recommended to rewire a 120-volt motor to run on 220 volts, as it can damage the motor and pose a safety risk. It is best to purchase a motor designed to run on 220 volts to ensure proper functioning and safety.
Yes, but the 600 volts would have to be transformed down to 480 volts. Direct connection to the motor with 600 volts would overheat the motor to destruction.
No, the voltage of 500 volts is too high to operate a 380 volt motor.
No, they do not draw the same current. The current drawn by an electrical device is determined by the power (Watts) and voltage (Volts) using the formula: Current (amps) = Power (Watts) / Voltage (Volts). So, the 12 volt 50 watt bulb will draw higher current compared to the 230 volt 50 watt bulb.
If a 48 Volt club car electric motor requires 48 volts, then it should be given a 48 volt power source, or something close to it. Too many more volts and it may burn out; not enough volts and it may not run or it will try to draw too much power and burn out the power supply.
Running a device designed for 208 volts on a 240-volt power supply can damage the device due to the higher voltage. It's important to match the voltage specifications of the device with the power supply to prevent any harm or malfunction. Using a transformer to step down the voltage from 240 volts to 208 volts would be a safer option.
