Escape from the high current discharge 15. After escaping the airlock of the Starship Discovery you get to the Engineering room. However, you find an attack by an alien space probe from the future has overloaded the main power source (a fusion reactor). To restart the fusion reactor it needs a current discharge of 42 A but this will also give anyone in the room a fatal shock! It takes 4.8 seconds to get from the switch to the exit. To restart the reactor, you use an inductor-resistor timing circuit for which the maximum current is 104 A. Its resistance is 2.0 Ω and it has a variable inductor The circuit will will discharge when the current reaches 42 A. Calculate the inductance (in H) needed to ensure you have just enough time to escape (4.8 seconds) when you close the switch that energises the circuit.
