In 1934 the standards for the Abacot Ranger Duck breed in Germany were set under the name of Streicher-Ente. The Female Abacot ranger duck are normally lighter than the males. The average females weighs about 5.5 pounds (2.5 kg) and the male weighs 6.6 pounds (3 kg). Rarely will you find this Abacot ranger duck flying. In fact, the Abacot Ranger Duck are not at all good at flying. Features about the Abacot Ranger Ducks Bills.
Electric Field Mill An Electric Field Mill is an electro-mechanical device which measures the strength of a static electric field. One or more electrodes are alternately exposed to and then shielded from the field to be measured.
When the Hall probe is held so that the magnetic field lines are passing at right angles through the sensor of the probe, the meter gives a reading of the value of magnetic flux density (B). A current is passed through the crystal which, when placed in a magnetic field has a  Hall effect  voltage developed across it.hen the force on the charged particles from the electric field balances the force produced by magnetic field, the separation of them will stop. If the current is not changing, then the Hall voltage is a measure of the magnetic flux density. Basically, there are two kinds of Hall effect sensors.
