What are a few of the differences between resistance and resistivity?
Answer:
The resistance R of wire depends on both the size and shape of the wire and on the resistivity a physical quantity whose value characterizes the material of which the wire is made.
Where l is the length of the wire and A is the cross sectional are of the wire.
Classical free electron theory: The free electron theory of metals using classical laws was developed by Dude and Lorentz in the beginning of last century. That time the va

When does the Total mechanical energy remain constant?
Energy gap: 1.4ev at room temperature Its charactistics are very closely related to those of germanium. This is under stable, since Gallium is the third column neighbour and a
Explain physically how a p-n junction functions as a rectifier. Ans: When a P-N junction diode is forward-biased and applied voltage is increased from zero, hardly any current
How we can calculate the magnitude of electric field above a sheet charged with voltage V where we know the bulk conductivity and relative permittivity of the space above the sheet
Ammeters : Ammeters are used to measure current flow, as such they need to be inserted in series with the circuit under test so that the current to be measured flows through th
