A power supply may be implemented as a discrete, stand-alone device or as an integral device that is hardwired to its load. In the latter case, for example, low voltage DC power supplies are commonly integrated with their loads in devices such as computers and household electronics. Constraints that commonly affect power supplies include:

In a darkened room, switch the spdt switch back and forth between the ac and dc supplies, gradually increasing the dc supply until the students agree that the lamp is equally bright from both power supplies. Now compare the traces on the oscilloscope. The ratio of peak ac to steady dc should be about 1.4 (i.e. 2 0.5). 12 V. ac. supply. 25 V ...
