A: Alternating voltages means the phase factor must be considered.
A changing magnetic field generates an electric field and alternating currents are accompanied (or caused) by alternating voltages.
A two-phase system is archaic and you are unlikely to find it in use anywhere these days, so it is mainly of historical interest. A two-phase, three-wire system, consists of two phase voltages, displaced from each other by 90 electrical degrees, and a phase voltage which is 1.414 x phase voltage.A three-phase system consists of three phase voltages which are displaced from each other by 120 electrical degrees. In the case of a three-phase, three-wire, system, the line voltages are numerically equal to the phase voltages; in the case of a three-phase, four-wire, system, the line voltages are 1.732 x phase voltage.

Break down voltages happens at low voltages (.6 for silicon & .3 for germanium), whereas knee voltages at higher voltages. That's why its cheaper.
Digital
D.C. stands for direct current. A.C. is alternating current.
A changing magnetic field generates an electric field and alternating currents are accompanied (or caused) by alternating voltages.
Electric current from a generating plant is a alternating current transmitted at high voltages, but usually used at low voltages.
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
What two voltages are present on a peripheral power connector?
I'm not sure they're "voltages" but if you're talking about the circuits, then the two types are series and paralllel.
the cell will add all of the voltages to a lump sum.
Low loss transmission of power at high voltages for long distances then the ability to transform down to lower voltages near the point of usage, i.e. substations and pole transformers near residences.
Alternating current is not necessairly low voltage, on the controrary AC is more oftenly used for when high voltage is needed. Most power distribution systems (extremely high voltages) use AC because AC is easier to transform to high voltages (using the aptly named transformer). High voltage is needed for power distribution to decreases losses due to transmission.
Batteries are connected in series to add their voltages together. For example, two car batteries in series will give twenty four volts.
The transmission of electrical energy requires very high voltages (for a given load, the higher the supply voltage, the lower the load current). To increase/reduce these voltages, you need transformers. Transformers are AC machines; they do not work with DC.
