In the circuit shown in figure initially the switch is in position 1 for a long time, then suddenly at \( t= \)
\( \mathrm{P} \)
0 , the switch is shifted to position 2 . It is required
W
that a constant current should flow in the circuit, the value of resistance \( \mathrm{R} \) in the circuit.
(1) Should be decreased at a constant rate
(2) Should be increased at a constant rate
(3) Should be maintained constant
(4) Not possible
