to slip rings. The same part of the coil
0:02
is always connected to the slip rings.
0:04
The current in the slip rings changes
0:06
direction when the current in the coil
0:08
reverses. Thus, alternating current AC
0:11
the brushes shown in green in the
0:13
simulation parallel to the normal to the
0:15
magnetic field which is directed from N
0:17
to S and is parallel to the motion of
0:19
the coil. There is no change in the
0:21
magnetic flux. Therefore, no emf or no
0:23
voltage is induced in the coil and no
0:26
current flows in the coil. The coil cut
0:28
through the magnetic field which is
0:30
directed from N to S.
0:33
V and I increase to voltage V max and
0:35
current I max when the coil is
0:37
horizontal and it cuts the magnetic
0:39
field perpendicularly.
0:41
Difference is at maximum. The value we
0:43
use for AC is known as the root mean
0:45
square arms average. This is the same as
0:48
what the if the current and voltage are
0:50
functions of time. So they are always
0:52
changing then so will the power that is
0:54
dissipated in any maximum potential
0:56
difference maximum current and maximum
0:59
power are related to each other by the
1:01
following equation. The relationship V
1:04
RMS equals 2 I RMS * R is a useful
1:07
equation.
