Additional information

Motors and Generators

Question 36
Outline Thomas Edison’s strategy to discredit
Westinghouse’s electricity system.
Edison tortured and killed animals with electricity to
demonstrate the dangers of AC power.
He also had an AC electric chair built for the execution of
convicted criminals.

Question 37
Why are suspension insulators shaped like discs?
Disc-shaped insulators help to prevent the insulators from
getting wet, and prevent dirt and grime from building up.
Dirty, wet insulators can act like conductors.

Question 38
What are two mechanisms through which electrical power
can be lost during transmission?
Very long wires have a large resistance, so electrical signals
that they carry lose energy by heating up the wires.
No transformer is perfectly efficient, so some of the energy
carried by an AC signal passing through a transformer is lost.

Question 39
(a) Who developed the first AC generator?
Nikola Tesla ↙
(b) Which company sold the first AC generator system?
The Westinghouse Electric & Manufacturing Company ↙

Question 40
(a) What range of voltages are used for long distance power transmission?
Long-distance signals can travel through power lines at a
voltage as high as 330 kV. ↙
(b) What voltage is this signal transformed to for residential use?
240 V ↙

Question 41
Why is AC transmission a better alternative to DC
transmission?
High voltage signals can be sent long distances without losing
much energy.
AC signals can be “stepped up” to high voltages, but DC
signals cannot.
This makes AC power a better way to transmit electricity. ↙

Question 42
What does it meant to “step up” an electrical signal?
To “step up” an AC signal means to increase its voltage.
Transformers are used to “step up” a signal to very high
voltages so that it can be transmitted with little energy loss.
Once it reaches its destination, the electricity can be
“stepped down” by another transformer.

Question 43
Outline the conditions in which dry air can conduct electricity.
Usually, dry air behaves like an insulator.
However, every 10 000 V of potential difference between
two conductors allows a spark to jump 1 cm.
This huge electrical spark travels through dry air and allows it
to behave like a conductor.

Question 44
What is a lightning rod, and why is it important?
A lightning rod is an electrical wire connecting the top of a
tall building with the ground.
If lightning strikes the top of the tower, the lightning rod
carries the electrical charge safely to the ground, where it
dissipates.
This prevents the lightning from damaging the building or its
occupants.

Question 45
Outline the main uses of AC and DC power today.
The most important use of AC power is the transmission of
electric power.
Most household and commercial devices are designed to
operate using AC power at the mains voltage of 240 V.
Low-power devices like mobile phone chargers rectify the
mains signal to DC before using it.
Finally, all battery-powered devices use the DC signal
produced by the battery.
