A circuit diagram of the automobile ignition circuit is shown in
the figure. Consider the circuit characteristics that provide the
energy to ignite the fuel-air mixture in the cylinder. First, the
maximum voltage available at the spark plug,
vsp, must be high enough to ignite the
fuel. Second, the voltage across the capacitor must be limited to
prevent arcing across the switch or distributor points. Third, the
current in the primary winding of the autotransformer must cause
sufficient energy to...
