... Atoms of the same element can have different numbers of neutrons which in return makes the element’s mass different; the different possible versions of each element are called isotopes. For example, hydrogen has 2 isotopes. One has a mass number of “1” and is called hydrogen-1. The other has a mass ...

Make an Electromagnet For this experiment, you will need a battery
... complete circuit, the electrons will not flow. Electrons have a negative charge, so they induce a charge on other particles when they flow through a wire. Electrons can create a magnetic field, which turns the nail into a magnet that can pick up small metal objects. Questions (use pg. 310 as an addi ...

Mechanism of electric conductance in crystals
... Electric field applied: There is an electric force, F = e E exerting on any free electron. Electron still experiences very frequent random collisions. However, after each collision the electron’s velocity has a component toward the positive electrode (against the field direction) On average, the ele ...

... more resistors in parallel, the less resistance in the circuit. The smaller the resistor, the bigger part of the current flows through that resistor. The equivalent resistor for all the parallel resistors will be smaller than the smallest resistor connected in parallel. The equivalent resistor means ...

Electromigration
Electromigration is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms. The effect is important in applications where high direct current densities are used, such as in microelectronics and related structures. As the structure size in electronics such as integrated circuits (ICs) decreases, the practical significance of this effect increases.
