ICSE Class 10 - Ohm's Law Videos
Relationship between resistivity and resistance
This video explains the relation betweeen the resistivity and length of wire
- Practically,why does current decrease if length of conductor increases?
-
Find the magnitude of current through the 4\OmegaΩ resistor in the circuit shown.
-
Find the resistance between A and B.
- calculate the resistance of 1km long copper wire of radius 1mm
- what is ohm law ?
