A: A VOM can measure the voltage across the load. To test the current if the current surpasses the VOM range just add a very small resistor in series with the load and use ohms law to find the current since you have the voltage drop.
Yes.
Switched Mode Power Supply
It's like a spark plug, it needs higher voltage to transmit the power.
An analog meter will respond to linearly as current is present . digital meters cannot do that not until the conversion is complete. in essence an analog meter is human friendly as compared to a digital meter. both have their places in applications.
No, the transformer has to supply the load, whether it is light or heavy.
A multimeter has many parts. Some of these include the display, the controls, the probes, and the power source. Multimeters can be analog or digital.
Yes.
SMPS stands for switched mode power supply

Switched Mode Power Supply

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.
not all but there rare many of them in this usage
Rectification is the process of converting alternating current into direct current. The smoothest power supply is a 'switched mode' supply.

To check the amp reading on a 12-volt cooling fan, you'll need a multimeter set to the ammeter function. First, disconnect the power supply to the fan and then connect the multimeter in series with the fan by placing the multimeter leads between the fan's power source and the fan itself. Once the connections are secure, reconnect the power supply and turn on the fan to read the current in amps displayed on the multimeter. Ensure safety precautions are taken to avoid short circuits or damage.
