Motors and Generators

Question 46
Determine the net force on
this circular, current-carrying
loop.
The net force is the sum of all
forces acting on the ring, so
the net force is zero.

Question 47
This coil lies in a magnetic
field of 0.1 T, and a current of
2 A flows through it in the
direction shown. Find the
torque acting on the coil.

Question 48
In which direction will the DC
motor turn?
Clockwise, from our point of
view.

Question 49
A power station generates electric power at 120 kW. It sends
this power to a town several kilometres away through
transmission lines that have a total resistance of 0.40 Ω.
If the power is transmitted at 240 V calculate:
(a) the current in the transmission lines.
(b) the power loss in the transmission lines.

Question 50
A transformer coil has X coils in the primary coils and 5X in
the secondary coil. The input voltage is 40 V.
(a) Write an expression for the output voltage.
(b) Calculate the output voltage.

Question 51
If the primary coil of a perfectly efficient transformer has
5500 turns, how many coils are required in the secondary
coil to convert a 11 kV signal to a 240 V one?

Question 52
Compare step-up and step-down transformers.
Step-up transformers change low voltages into higher
voltages. They have more turns in their secondary coils than
in their primary coils, and their output current is lower than
their input current.
Step-down transformers change high voltages into lower
voltages. They have fewer turns in their secondary coils than
in their primary coils, and their output current is higher than
their input current.

Question 53
Explain why a 240 V transformer may burn out if connected
to a 240 V DC signal.
A DC signal cannot be transformed, so there will be no back
emf induced by the secondary coil of the transformer.
This means that the transformer will short-circuit and burn
out.

Question 54
Explain the motion of a magnet when it is dropped into a
tube of non-magnetic metal.
When a magnet is dropped into a metal tube, it slows down
and passes through the tube very slowly before falling out of
the bottom.
When a magnet moves near a metal, its changing magnetic
field induces eddy currents in the metal.
These eddy currents produce a magnetic field that opposes
the motion of the magnet, so the magnet slows down.

Question 55
A signal with a power of 120 kW is stepped up to 11 kV
without loss, and then sent through long transmission lines
that have a total resistance of 0.40 Ω.
(a) Calculate the current in the transmission lines.
(b) Calculate the power loss in the transmission lines.
