← A 6 V cell and a 2 V cell, each with an internal resistance of 0.5 Ω, are joined in series but facing opposite ways (positive terminal to positive terminal), together with a 3 Ω resistor, to make a single loop. The current in the loop isA coil has an inductance of 5 H and a resistance of 10 Ω. It is connected through a switch to a 20 V battery whose internal resistance is negligible. The current in the coil 0.5 s after the switch is closed is closest to →
