5. One of the results of Faraday's observations on induction was the spark gap. This is just a transformer that steps up the primary voltage to many thousands of volts in order to produce electric sparks several inches long. Let's do a little analysis of a spark gap. The primary coil of this spark gap has 100 turns of copper wire with a resistance of 2.6 2. The secondary coil consists of 30,000 turns of wire with a resistance of 5 k.(The following calculation is VERY approximate since there are many complicating factors we have not discussed.) When a 12 V battery is connected to the primary coil what current will run through the coil? a. b. C. What will be the strength of the magnetic field through the primary coil? If the primary coil has a radius of 1 cm, what is the magnetic flux through the coil? d. When the battery is disconnected, assume it takes 2 milliseconds for the magnetic field to fall to 0. What voltage is induced in the secondary coil?
