Can SMPS work in DC supply?
Yes. Input DC voltage would be root2 times the input AC voltage.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
How do you measure Input high voltage?
You can measure high voltage by using Potential Transformer (PT). or by using utility meter or power manager. ANSWER: Adding a hi resistance in series with a low resistance and measuring that voltage drop. If the resistance is known then current is determined and the source can be calculated. transformers do not work well with DC,
How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
Does watt meter use for ac and dc?
No, on dc the power is measured by the produce of the voltage and current so there is no need for a wattmeter, which would not work on dc anyway.
Am using a photocell in a 9volts dc circuit will this be enough to produce an output?
A: A photocell is like a variable resistor it will change resistance with light the ratio of dark:light resistance decides the output. So yes it should work with 9volts
Can a fan work on a DC voltage?
Yes, if the fan is designed to work on DC voltage, otherwise no.
Can you harness the 1 100th volts that comes from your tongue using transformers and a dc to ac converter?
No. Transformers only work with AC. Tongue-voltage is DC.
How dc voltage changes into ac voltage?
yes it is possible.we can convert dc into ac using inverter.this inverter is diff than our home inverter or using commutator.
Can SMPS work in DC supply?
Yes. Input DC voltage would be root2 times the input AC voltage.
Can you harness the 1 100th of a volt that comes from your tongue using transformers?
No. Transformers only work with AC. Tongue-voltage is DC.
How does ac dc power supplies work?
The mains to the house is an alternating current and this high voltage is stepped down using a transformer. The low voltage secondary alternating current is converted to direct current using 4 diodes wired as a bridge rectifier. The 'lumpy' direct current is smoothed using an electrolytic capacitor to smooth the resulting dc. It may need to be voltage regulated if the circuits it feeds are voltage sensitive.
How can be a DC voltage source output voltage made half of its output voltgae?
By using something called a voltage divider.
Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?
You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.

How can you on laptop wihtout using battery?
we can use a dc voltage directly from a dc source with parameters equal that of the battery
How do you make ac into DC in a ac transformer?
You can not change AC into DC using a transformer. A transformer changes the voltage levels. To change AC into DC, you would need a rectifier. To change that into smooth DC you need a capaciter and a voltage regulater
