According to Ohm's law dIdV=−r and V=ε if I=0 [As V+Ir=ε ] ∴ Slope of the graph =−r and intercept =ε
NEET UG 2009 — Physics Electromagnetism
A student measures the terminal potential difference (V) of a cell (of emf ε and internal resistance r ) as a function of the current (I) flowing through it. The slope and intercept of the graph between V and I, then respectively, equal

Two point charges +2μC and -2μC are placed 10 cm apart. The electric field at the midpoint is:
A parallel plate capacitor made of circular plates is being charged such that the surface charge density on its plates is increasing at a constant rate with time. The magnetic field arising due to displacement current is :
Two identical charged conducting spheres $A$ and $B$ have their centres separated by a certain distance. Charge on each sphere is q and the force of repulsion between them is $F$. A third identical uncharged conducting sphere is brought in contact with sphere A first and then with B and finally removed from both. New force of repulsion between spheres $A$ and $B$ (Radii of $A$ and $B$ are negligible compared to the distance of separation so that for calculating force between them they can be considered as point charges) is best given as :
The electric potential at distance r from a point charge q is V = q/(4πε₀r). The electric field E is:
The current passing through the battery in the given circuit, is :
