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.
a) Heat produced or absorbed at a junction is proportional to the current by the junction. b) This effect is produced when current is passed by junction of suitable materials.
It is based on the photovoltaic effect. One of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and gets absorbed. It changes solar
