Capacitors: Energy Storage and Geometry-Dependent Sensors

This lecture covers the concept of capacitance and how capacitors store electrical energy, including the calculation of capacitance. It also explores scenarios where the potential difference or the charge in a capacitor is doubled, affecting the capacitance. Additionally, it delves into the application of capacitors in pressure sensors, where capacitance varies with geometrical changes, impacting the measured voltage difference. The lecture concludes with a discussion on the relationship between capacitance and potential in sensing under-and overpressure conditions.
