primary current in a sentence

Examples

1. To the extent other windings are then " loaded " by drawing current to a load, the primary current will increase above the exciting current.
2. Also, the primary current rating of a current transformer should not be exceeded or the core may enter its non linear region and ultimately saturate.
3. When the armature has moved far enough, the pair of contacts ( " K " ) in the primary circuit open and disconnect the primary current.
4. These were often driven by a separate electromagnet or motor, which allowed the interruption rate and " dwell " time to be adjusted separately from the primary current.
5. In this figure, blue dots indicate where B flux from the primary current comes out of the picture and plus signs indicate where it goes into the picture.
6. In the initial systems, points were still used but they handled only a low current which was used to control the high primary current through a solid state switching system.
7. When battery power is applied, the coil acts as an electromagnet; the magnetic field from the core pulls the springy iron arm, opening the switch contacts, interrupting the primary current.
8. At higher primary currents, a great deal of material can be removed by sputtering, allowing precision milling of the specimen down to a sub micrometer or even a nano scale.
9. The alternating magnetic field induces an alternating voltage across the secondary terminals but until they are connected to a load there is no secondary current nor change in the primary current.
10. The low voltage output winding mirrors the sawtooth of the primary current and, e . g . for television purposes, has fewer turns than the primary, thus providing a higher current.
