Why do capacitors charge exponentially?

A capacitor is an electronic component that stores electrical energy in the form of an electric field. It is made up of two conductive plates separated by an insulating material called a dielectric. When a voltage is applied to the capacitor, one plate accumulates positive charge while the other accumulates negative charge.
A capacitor works by storing electrical energy in an electric field between its two plates. When a voltage is applied, one plate becomes positively charged and the other becomes negatively charged. This creates an electric field between the plates, which stores the electrical energy. The insulating dielectric material between the plates prevents the charges from flowing back and forth.
The unit of measurement for capacitors is the farad (F). However, capacitors are typically measured in smaller units such as microfarads (μF) or picofarads (pF).
Capacitors are used in electronic circuits for a variety of purposes, including energy storage, filtering, and timing. They can be used to smooth out voltage fluctuations, block direct current while allowing alternating current to pass through, and control the timing of signals. They are also commonly used in power supplies and audio equipment.
Choosing the right capacitor for a circuit involves considering factors such as capacitance, voltage rating, and frequency. The desired capacitance and voltage rating will depend on the specific application of the circuit, while the frequency will determine the type of capacitor needed (i.e. electrolytic for low frequencies, ceramic for high frequencies). It is important to consult a datasheet or seek advice from an experienced engineer when choosing a capacitor for a circuit.
