Solved Suppose an RC (resistor-capacitor) circuit is charged
Suppose an RC (resistor-capacitor) circuit is charged and then discharged after a certain amount of charging. The amount of charge in the capacitor during charging is given by q (t) = Cε (1 − e − t / τ) and during discharging, by q (t) = 2 Cε e − t / τ sinh (t ∗ / τ), where C is the capacitance (in F, or farads) of the capacitor, ε is the voltage (electromotive force, or …

Assume that the capacitor is fully discharged prior to t=0. The switch is closed at t=0 connecting the voltage source to the rest of the circuit. What is the steady-state value of the voltage across the capacitor, VC(t), after the switch is closed for a long time? Put your answer in the box below, without the units (Volts).
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by

What is a Capacitor Discharge Ignition (CDI) & Its Working
The rectifier within the charging circuit can avoid the discharge of the capacitor before the ignition moment. Once the triggering circuit gets the triggering signal, then this circuit will stop the working of the charging circuit & allows the capacitor for discharging its o/p fast toward the ignition coil of low inductance.

Question: Q2. The capacitor in the circuit below is totally discharged when the switch is thrown into position 1 . The switch remains in position 1 for 10 ms and is then thrown into position 2 . What is the capacitor voltage after 5 ms from the moment the switch was thrown into position 2 ?
-Current goes to 0-Capacitors are charged through a resistor. Initially, when the charge is zero, the potential across the capacitor is zero. Hence maximum current flows through the circuit.-When a capacitor is fully charged, then the potential difference across the capacitor equals the voltage source. So there will be no current in the circuit.

A small resistance (R) allows the capacitor to discharge in a small time, since the current is larger. Similarly, a small capacitance requires less time to discharge, since less charge is stored.
