Extracted text: In a car ignition system, a 12 V battery whose internal resistance was neglected is connected to the primary of the ignition coil. The total resistance of the circuit is 0.1 Q. The switch remains closed for 0.005 seconds before opening the circuit. The current would take if the switch was always closed what will be the value of the inductance (L) in order to reach 90% of the value (maximum current value) calculate.
