Final answer:
The capacitor in a high-tension magneto is part of the internal circuit which impacts impedance and participates in timing. Its effects on impedance vary with frequency, being more significant at low frequencies. Additionally, capacitors can determine filtering characteristics when used in conjunction with inductors in electrical circuits.
Step-by-step explanation:
The electrical location of the capacitor in a high-tension magneto is within the magneto’s internal circuit. It typically serves as a storage device for electrical energy and is a component of the timing mechanism within the magneto system, which generates high voltage for spark plugs in an engine. High-tension magnetos are essential in providing a reliable spark to ignite the fuel-air mixture in the cylinders of an engine. Capacitors in such circuits can influence impedance (Z), depending on frequency. At low frequencies, the capacitor significantly increases impedance, whereas at high frequencies, its effect is considerably smaller. This is due to the capacitive reactance, which varies inversely with the frequency, meaning the higher the frequency, the less capacitive reactance impedes the circuit. In the context of filter applications, swapping capacitors with inductors in specific circuits can designate the circuit as either a low-frequency or high-frequency filter, showing the versatile role of such components in affecting electrical properties and behavior within various circuit designs.
