Well it depends on several things, does it need to be AC or DC? how much amperage must it be able to supply?

For a very basic power supply you could us:

A Step-down transformer

A bridge rectifier (4 diodes of sufficient voltage and amp rating)

Two capacitors; one at 1000uF and one at 0.01uF

A 9 Volt voltage regulator (LM7809 is good)

Depending on transformer and rectifier, this'll deliver 9V at up to 1A

Could you please help me I am looking to use 24 par 64 500w lighting bulbs for our light show ive been told i need a 63a 3 phase supply could you tell where i could get one and how much it would cost?

Ask your local mains electricity power supply company to install a 63 Amp 3-phase supply at your site. It is not something you can buy in a shop like a battery. It is an electricity supply service that is different to a standard domestic home mains supply but is quite normal for places which use machinery such as workshops, factories, etc.


What multimeter readings set to measure resistance indicate an open circuit and short circuit in the primary and secondary windings of a mains power transformer. And what readings show good?

You cannot use an ordinary multimeter to assess the difference between a normal power transformer winding and a shorted power transformer winding. You need a Q meter and/or to power it up at a reduced voltage with limited current to see what happens. Note that a shorted power transformer is capable of exploding, so you need to take appropriate safety precautions.

How is it possible your power supply is faulty multimeter test says acceptable?

A multimeter draws next to no current, so will not effectively test the power supply under load. The voltage on the meter is averaged out and so will not show ripple current, or spurious dips in the supply. You will need an oscilloscope to check for ripple current (poor smoothing) and the supply needs to be under a load.

Can you use a 220 laptop in a 110 outlet?

The laptop has a power supply that connects between the laptop and the wall outlet. Looking at the power supply, the input voltage will show a working voltage from 100 to 240 volts. You may need a pin changing adapter because the pin configuration is different between 110 outlets and 220 volt outlets. Get past the pin configuration difference the computer will operate on both voltages through the power supply as long it is in the voltage range stated above.

Can battle tanks run on electric?

In theory - yes. However this does not show to be practical, as the power supply for a vehicle that size and weight would need to be massive and would in turn only increase the size and mass of the tank, making it slower and a larger target.
