Key Idea To convert a galvanometer to ammeter a small resistance is connected in parallel to the coil of the galvanometer. Here, G1=60Ω,Ig=1.0 A,I=5 AIgG1=(I−Ig)SS=I−IgIgG1=5−11×60=15Ω Putting 15Ω resistance in parallel.
NEET UG 2009 — Physics Electromagnetism
A galvanometer having a coil resistance of 60Ω shows full scale deflection when a current of 1.0 A passes through it. It can be converted into an ammeter to read currents upto 5.0 A by

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 :
