Because we can’t trust that the USB power is always +5v and not less, we couldn’t use only one charge pump to double it, so we needed two charge pumps with more than +5v operating voltage range. We found only one charge p ...

... The total resistance of all (about 1700) splices in the circuit is rather unknown. I expect a value between 350 and 900 nW. We should try to deduce this value by measuring the voltage over all the magnets at several DC current levels (e.g. during the ‘current loop stability’ tests). The accuracy of ...

Alternating current



Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.AC is the form in which electric power is delivered to businesses and residences. The usual waveform of alternating current in most electric power circuits is a sine wave. In certain applications, different waveforms are used, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information encoded (or modulated) onto the AC signal, such as sound (audio) or images (video).
