JEE Mains · Physics · STD 12 -6. Electromagnetic induction
A part of a complete circuit is shown in the figure. At some instant, the value of current \(I\) is \(1\, A\) and it is decreasing at a rate of \(10^{2}\, A s ^{-1}\) The value of the potential difference \(V _{ P }- V _{ Q }\) (in volts) at that instant, is.
- A \(33\)
- B \(28\)
- C \(38\)
- D \(23\)
