NCERT lines NEET asked again and again

Read these lines from your NCERT book twice: NEET has built questions on each of them more than once.

In a metal carrying about an ampere, electrons creep at only a fraction of a mm/s , given by v_d = I/(neA); mobility is μ = v_d/E.
AIPMT 1991NEET 2020NEET 2023
A cell delivering current gives V = ε − Ir, so terminal voltage is less than emf ; on a V-I graph slope is -r , intercept ε.
AIPMT 2009NEET 2022NEET 2024
When a wire is stretched at constant volume, R ∝l² so doubling length gives 4R, while resistivity stays unchanged .
AIPMT 2008NEET 2013
Metals: resistance rises with temperature; semiconductors and insulators have negative α and their resistance falls.
NEET 2020NEET 2022
The junction rule is conservation of charge ; the loop rule is conservation of energy . NEET asks which law matches which.
AIPMT 2006AIPMT 2010
For a fixed appliance resistance, P ∝V² ; a heater rated 400 W at 220 V gives about 331 W on 200 V.
