Question
The current i in an inductance coil varies with time, t according to the graph shown in fig. Which one of the following plots shows the variation of voltage in the coil with time
The correct answer is:
According to i – t graph, in the first half current is in-creasing uniformly so a constant negative emf induces in the circuit.
In the second half current is decreasing uniformly so a constant positive emf induces
Hence graph (c) is correct
