The __________ coil handles a high voltage of 500V-600 volts on the primary side.

• A. Inductive discharge
• B. Capacitive discharge
• C. Spark discharge
• D. Magnetic discharge

Answer: (B)

Capacitive discharge ignition stores energy in a high-voltage capacitor and dumps it into the coil’s primary. When the capacitor is charged to around 500–600 volts, that voltage is delivered into the primary winding in a rapid burst, causing a fast rise in current. This quick change in current creates a strong magnetic field and, when it collapses, induces a very high voltage in the secondary winding to produce a strong spark. The key idea is that the energy is held in a capacitor at high voltage and released suddenly into the coil, which is why this coil type handles hundreds of volts on the primary side.

Inductive discharge uses the battery to build magnetic energy in the coil and releases it when the circuit opens; the primary voltage during discharge is not maintained at hundreds of volts. Spark discharge isn’t a coil type, and magnetic discharge isn’t a standard term for this setup.
