Cathode-ray-tube oscilloscopes have parallel metal plates inside them to deflect the electron beam. These plates are called the deflecting plates. Typically, they are squares 3.0 cm on a side and separated by 5.0 mm, with vacuum in between. What is the capacitance of these deflecting plates and hence of the oscilloscope? (Note: This capacitance can sometimes have an effect on the circuit you are trying to study and must be taken into consideration in your calculations.)
What is physics Physics is the study of fundamental laws of nature. These laws can be expressed as mathematical equations. These laws can appear quite simple, but much complexity can arise from them. In physics we use the SI system for unit labeling Length is measured in meters (m) Mass is measured in kilograms (kg) Time is measured in seconds (s) Length is standardized using the distance traveled by light in a vacuum in 1/299,792,458 of a second Some typical lengths (to 1 significant figure): Diameter of our Galaxy: 8 x 10 2m Radius of the Earth: 6 x 10 6m Length of a Football Field: 1 x 102m Diameter of a CD: 1 x 10 -1m Diameter of a hydrogen atom: 1 x 10 -m0 Diameter of an electron: 3 x 10 -1m One kilogram
