ElectroMagnetic InductionHard
Question
A circuit element is placed in a closed box. At time t = 0, constant current generator supplying a current of 1 A, is connected across the box. Potential difference across the box varies according to graph shown in figure. The element in the box is
Options
A.resistance of 2Ω
B.battery of emf 6V
C.inductance of 2H
D.capacitance of 0.5 F
Solution
Constant Current supply is Crucial point of the question.
Compare it in 3 Circuit element: Resistance , Inductor , capacitance
For resistance EMF will be constant, For Inductor No EMF as No change in current
Only can be capacitor as current flow charge will increase as V = Q / C
