At the moment t = 0, a 27.0 V battery is connected to a 5.00 mH coil and a 6.00 Ω resistor.
(a)
Immediately thereafter, how does the potential difference across the resistor compare to the emf across the coil? (Enter your answers in V.)
(b)
Answer the same question about the circuit several seconds later. (Enter your answers in V.)
(c)
Is there an instant at which these two voltages are equal in magnitude?
Yes
(d)
If so, when? Is there more than one such instant? (Enter all possible times in ms as a comma-separated list. If there are no such instants, enter NONE.)
ms
(e)
After a 3.70 A current is established in the resistor and coil, the battery is suddenly replaced by a short circuit. Answer questions (a) and (b) again with reference to this new circuit. (Enter your answers in V.)
