When a strong bar magnet is pushed into a coil of insulated copper wire connected to a galvanometer, we will observe a deflection in the galvanometer in

A boy records that 4000 joule of work is required to transfer 10 coulomb of charge between two points of a resistor of 50 Ω. The current passing through it is:

The least resistance obtained by using 2 Ω, 4 Ω, 1 Ω and 100 Ω is:
