The national grid uses step-up transformers to produce very high voltages in long cables that link towns and cities. Why is this?
People are less likely to steal the electrical energy because it is dangerously high voltage.
The transformers step up the power delivered by the same ratio as the step up in voltage.
Houses and offices need this very high voltage to operate
Less current is needed, and therefore there is less power loss in the cables.
Which statement is correct?
Particles always move around past each other, and they move fastest in gases and slowest in solids.
Particles in solids vibrate in fixed positions; particles in liquids and gases move around past each other
Particles vibrate about fixed positions in solids and liquids, and move around in gases.
Particles in solids do not move at all; particles move slowly in liquids and faster in gases
