The given figure shows a part of a bigger circuit. The rate of change of the capacitor is
6 mF and is decreasing at the constant rate
0.5 mFs−1. The potential difference across the capacitor at the shown moment is changing as follows
dVdt=2Vs−1,
d2Vdt2=12Vs−2 and the current in the
4Ω resistor is decreasing at the rate of
1mAs−1. What is the potential difference (in
mV) across the inductor at this moment?
