Question

A long, fine wire is wound into a coil with inductance 5 mH. The coil is connected across the terminals of a battery, and the current is measured a few seconds after the connection is made. The wire is unwound and wound again into a different coil with L = 10 mH. This second coil is connected across the same battery, and the current is measured in the same way. Compared with the current in the first coil, is the current in the second coil. ( Select all of them that applies)

A- Twice as large

B- One-Fourth as large

C- Uncharged

D- Half as large

E- Four times as large
