What is the function of the condenser in an ignition system?

The function of the condenser in an ignition system is primarily to control the current through the breaker points. When the breaker points open, a high voltage is generated in the ignition coil that can lead to sparking or arcing across the points. The condenser acts as a reservoir for electrical energy, storing the current momentarily and then releasing it back into the circuit. This process helps to prevent arcing at the points, which can lead to premature wear or failure of the ignition system components. By controlling the current flow and smoothing the operation of the ignition system, the condenser ultimately contributes to more reliable spark generation and improved engine performance.

The other options do not accurately reflect the role of the condenser. It does not amplify the current; rather, it smooths the electrical flow. It is not related to fuel filtration or the operation of the starter motor. Therefore, the answer regarding the condenser's function in controlling current and preventing sparking is correct.
