What is electrical conductivity in
0:02
physics? Definition. Electrical
0:04
conductivity is the measure of how
0:06
easily electric current can flow through
0:09
a material. It shows how well a
0:12
substance allows electrons to move.
0:14
Explanation: Every material contains
0:17
tiny charged particles called electrons.
0:20
In good conductors like copper, these
0:22
electrons move freely, allowing current
0:25
to pass easily. In poor conductors
0:28
insulators like rubber or plastic, the
0:30
electrons are tightly bound making it
0:33
difficult for current to flow.
0:35
Connectivity depends on the material's
0:37
nature and temperature. As temperature
0:40
increases, the vibration of atoms
0:42
usually increases, slowing down
0:44
electrons and reducing conductivity in
0:47
metals. However, in semiconductors,
0:50
conductivity increases with
