63 | Some basic theory that will help<br />

Voltage levels in space go far beyond those that drive lightning strikes.<br />

Here in our biosphere on Earth we have always been safely protected<br />

from those much more extreme forces and so are understandably<br />

unaware <strong>of</strong> them. The fact is, the levels <strong>of</strong> electrical power in space are<br />

impossible for us humans to appreciate. This limitation has, however,<br />

not stopped the study by some scientists <strong>of</strong> these extreme levels <strong>of</strong><br />

energy. We can and do manufacture on small scales in our electrical and<br />

plasma science laboratories, very powerful levels <strong>of</strong> voltage pressure<br />

indeed. The person most famous in this area <strong>of</strong> research is probably<br />

Nicola Tesla, a man I will mention again later.<br />

An important thing to point out at this stage is the term ‘polarity’. In electric circuits there normally exists<br />

a voltage difference between one area and another, a condition that can cause current to flow in a particular<br />

direction between those areas. Polarity is what we use to represent the state <strong>of</strong> voltage (charge difference) that<br />

will dictate the direction <strong>of</strong> current flow. We refer to this charge state by the terms positive and negative, just like<br />

when we were talking about charges associated with atoms and their sub-atomic building blocks.<br />

One side <strong>of</strong> an electric circuit can be more positive<br />

or negative than the other side, but this is a relative<br />

thing because voltages can constantly vary. If a<br />

positive ‘node’ (point or area) in a circuit varies to<br />

become more negative, any other node previously<br />

seen as negative in relation to it might then be seen<br />

as positive. Try to follow this explanation in the<br />

diagram provided here. It is helpful to have an<br />

appreciation <strong>of</strong> this variable relationship in your<br />

mind when we talk about current flow, especially<br />

if we consider current flow in plasma in space.<br />
