A circuit consists of an ideal DC voltage source of 10 volts, an inductor with an inductance of 2.0 millihenries, and a fuse which causes the circuit to become open when the current reaches 12 amperes, all in series. The current through the circuit is initially 0 amperes. How long, in seconds to two significant figures, will it take until the fuse opens the circuit? Give your answer in scientific notation.
