CBSE X Physics Electricity
how can we explain the difference between the resistivity and the resistance of the conductor?
CBSE X Physics Electricity
Actully...i want to know that Why resistance is actually needed???
CBSE X Chemistry
is power directly proportional to the resistence or inversely proportional to resistence?

@ wires of resistence a & b of equal mass and same material are taken the diameter of wira a is half of diameter b if the resistence of wire a is24 ohms find the resistence of wire b

sir can you explain me this question
A piece of resistance wire has a resistance 16 ohm.Its diameter is doubled.what will be the new" R"
