An induction coil in an automobile is much like an ac transformer that boosts low voltage to high. The 12 V from the battery is de, so a device interrupts the current on and off, producing a changing current equivalent to ac. Find the ration of primary to secondary turns to boost 12 V to 24,000V required for the spark plugs.
