Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
The flux linkage of a coil is
NΦ
Φ/N
B/N
BA
2.
A 400-turn coil has 2.0 × 10−4 Wb through each turn. The flux linkage is
2.0 × 10−4 Wb turns
0.80 Wb turns
5.0 × 10−7 Wb turns
0.080 Wb turns
3.
For a coil rotating at constant speed the flux linkage is zero when the
coil's normal is parallel to B
plane of the coil is parallel to B
coil is stationary
plane of the coil is perpendicular to B
4.
A coil is turned through 180° from perpendicular to the field. The change in flux linkage is
2NBA
−NBA only
0
NBA
5.
Doubling the number of turns of a coil in the same field and orientation makes the flux linkage
four times
unchanged
twice
half
6.
The gradient of a graph of flux linkage against time gives
the current
the resistance
the induced e.m.f.
the flux density
