How the do calculate the power developed by a 12v regulated power supply?

The word "developed" is slightly odd in this context. If the power supply provides a current to some instrument or device, the power supplied is the voltage multiplied by the current. The power supply will also consume some power itself to do this job. The total power consumed (provided to the power supply) equals the input current multiplied by the input voltage.


WHY IS MY 1988 tornado instrument panel comes on and goes off?

How can you measure the ampere or watt for power supply?

You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.
