Prepare a booklet titled ‘Electrical Safety Awareness’ that has the following sections:Section 1 – AC and DC current
Explain the differences and similarities of the properties of AC and DC current in simple
circuits
Use diagrams based on simple laboratory experiments to illustrate how both AC and DC
electricity are produced
Illustrate, with a fully labelled graph, the difference between AC and DC electricity
as seen using an oscilloscope.
AC generators tend to be made with the equipment of the device that is known as the
commutator that will then produce the direct current. Then for the DC the batteries will be
provided for this due to the chemical reaction that occurs inside of the battery for this. The
similarities between the current that tend to use the free electrons to be used as the charge in
the current for this as electrons then produce the energy that can move around and that will
then give energy that isn’t needed as when its passed through that of the circuit. In contrast,
the direct current where the voltage for this tend to show that its always constant and that the
electricity tend to be flowing through the direction of this. Because of the alternating current
for the voltage that will be changing to the positive then negative and the opposite. The
direction of the current tend to change within the timings.
The diagram shows for the AC for there comes through out of the walls of it.
The diagram shows that the DC comes out where it comes out of the battery for this.
(energy, 2022)
(Precision, 2022)
,Here in this figure shows the DC current for the direction of the current of the voltage for that is
constant. Then this shows the AC for this shows the direction of the current called that is switches on
time and then it will be switched on.
Carry out simple practical activities to produce both DC and AC electricity and record
your findings.
Explain, using diagrams, how Fleming’s Left Hand Rule (FLH) applies to electric
motors and how Fleming’s Right Hand Rule (FRH) applies to AC generators.
(Technology, 2022)
The current tends to be carrying for the conductor that is laying in the magnetic laying in for
the magnetic field and that has the mechanical force that will be applied to the conductor to
that will be pushed away from the field. That there is the direction of the force to then be of
the opposite to that of the direction of the current and that of the perpendicular to that of the
direction of that is the magnetic field. Because this rule is used to find the direction of the
current for the conductor laying in for the magnetic field. Because by the thumb, index finger,
and for the middle finger of the left hand at right angles for this at 90 degrees to that of each
other. For there being the thumb for the applied force for the motion and that the first index or
that of the forefinger that is illustrated that showing the line of flux then that of the second
middle that showing the direction of there is of the current. That of electrical motor known
that of the left hand rule that electrical motors and that motor rule.
, The conductor that is moving of the magnetic field that of the EMF of that is induced for it
and that the direction of the EMF and that of the current. That of the thumb, forefinger, and
middle finger that tend to become perpendicular to each other to make at least 90 degrees.
For there is the forefinger that points to the direction of the field and that the thumb will
point to the direction of the conductor and that of the middle finger that will then point to the
direction of the induced current for this. This tends to be applied for the electrical generators
and that of the alternators.
Discuss the need for a split ring commutator in a DC motor.
Describe how DC electricity can be stored.
The DC motor tends to be transformed to the electrical potential energy into that of the kinetic
energy that is used for the application of the DC. As such this is due to the electric motor that
will then produce the rotational motion of that will be passed a current that is through the coil
and that in a magnetic field. Also, for the magnets to provided the external magnetic field that
is in the coil that will be rotating through the magnets to that of the stator this is due to being
fixed to the casing of the motor that tends to be stationary for this. Also, the fact that the stator
can be consisted of the pair of the electromagnets and that of the coil to be connected to the
source of the EMF through that of the carbon brushes and that of the spilt commutator Then
there is the coil that is the wound onto that of the frame that is due to being known to that of
the armature and that of the coil that will then be consisted of the turns for this as the rotor for
this. Because the armature axle will then be extended from the motor to the casing and that
will be connected to the spilt ring commutator. There lays the spilt-ring commutator and that
will be brushed then the formation of the mechanism for this will then be enabled for the
current to then change to the direction that occurs through that of the coil because it turns half
which will then supply that of the AC to DC current. That having the spilt ring. Commutator
as having it reverse that is due to the current of at least 180 degrees and that then ensures that
the torque will then have to continue in for the same direction. There being the spilt ring
commutator will then be connected to that of the armature (Learn, 2022). To be able to store
the electricity is by having the capacitor and that of the rechargeable battery. This occurs due
to the batteries that tends to be used to then create the DC (Kurtus, 2018).
