Write out the transformer law equation.

induction motor.gifThis device has stators (several fixed electromagnets arranged in pairs around the rotor) and a rotor (located in the middle of the stators and is composed of an iron core surrounded by coils).  Since the stators are fired sequentially, this creates a moving magnetic field that the rotor constantly turns itself trying to find magnetic alignment. What type of device is this?

The rotating anode is typically composed of which of the following materials? Choose one or multiple correct answers.

The transformer changes

The more current passed to the filament, the hotter it becomes, and the more electrons are boiled off. The term descibing this process is _____________________?

Which number labels the step down transformer in the x-ray circuit diagram?  image00350581a48.jpg

The SI unit for current flow, or of amount of charge per second, or how many electrons are flowing past a particular point in the current in 1 second is…?

What stays the same in isotopes?

Electric fields can be described as and magnetic fields can be described as
