Figure shows a part of a bigger circuit. The capacity of the capacitor is 6 mF and is desaesing at the constate rate 0.5 mF/s. The potential difference across the capacitor at the shows moment is changing as follows: dVdt=2Vs−1, d2Vdt2=12VS−2 The current in the 4Ω resistor is decreasing at the rate of 1 m A/s. What is the potential difference (in mV) across the inductor at this moment?
