What does “Ohm's law” actually mean in Current Electricity, and why does it matter for JEE?
for many conductors V = IR at constant temperature.
In simple words: for many conductors V = IR at constant temperature. Getting Ohm's law clear matters because JEE questions on Current Electricity usually test this idea directly, not just a formula you memorised.
Key point
Ohm's law
Common mistake
assuming every component is ohmic (a diode or bulb filament is not).
Memory tip
Ohm's law is a property of some materials, not a universal rule.
