The diagram shows an ideal (zero internal resistance) DC source connected to three identical resitances and a switch. In the diagram, the switch is open. If initially, the switch is open, what happens to current I1 and I2 after the switch is closed? I1 increases, decreases, or stays the same and I2 increases, decreases, or stays the same?

The figures below show six circuits which consist of identical ideal batteries, resistors, and inductors. All of the switches are closed at the same time. Rank the circuits based on the current through the battery a very long time after the switch is closed. Rank from largest to smallest. To rank items as equivalent, overlap them.

To ignite a mixture of gasoline and air inside an internal combustion engine--like in your car--a spark is generated by a high voltage across the spark plug, usually in the 10's of thousands of volts, but the battery is only 12 V. This massive increase in voltage is achieved through a transformer called the 'ignition coil'. A typical ignition coil has a primary with 300 turns wrapped around a radius of 2 cm over a linear distance of 15 cm . The secondary has 60,000 turns of wire over the same cylinder. The spark is generated when the current is suddenly shut off to the coil. Assuming that the magnetic field is uniform inside the primary and secondary, and that all of the magnetic field lines that go through the primary go through the secondary, what voltage is generated in the secondary coil if the current drops from 10 A to 0 A at a steady rate over the course of 50 mirco-seconds? Give your answer to 2 significant digits.
