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.

When switch is off of power supply output shown on the multimeter is negative voltage from power supply?
Yes.
What is the full form of SMPS?
Switched Mode Power Supply
Why diac should be tested with power supply and cannot be tested with digital multimeter?
It's like a spark plug, it needs higher voltage to transmit the power.
What are the disadvantages of a digital multimeter?
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.
Is the power transformer switched off under light load conditions?
No, the transformer has to supply the load, whether it is light or heavy.
Part of multimeter?
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.
When switch is off of power supply output shown on the multimeter is negative voltage from power supply?
Yes.
What is the most efficient way to determine if your power supply is bad?
test it with a multimeter
What does SMPS stand for?
SMPS stands for switched mode power supply
What is the full form of SMPS?
Switched Mode Power Supply
What tool can you use to troubleshoot power supply issues measure current resistance or voltage?
multimeter
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.
Is a phone charger a switched mode power supply?
not all but there rare many of them in this usage
What is rectification and which power supply provides a smoother form of rectification with less fluctuation?
Rectification is the process of converting alternating current into direct current. The smoothest power supply is a 'switched mode' supply.
Why diac should be tested with power supply and cannot be tested with digital multimeter?
It's like a spark plug, it needs higher voltage to transmit the power.
