You need to be little more specific to get an accurate answer. Capacitance in which circuit?
Thanks.
Capacitance will block DC
as it acts ideally as open circuit for dc
A: Those diodes are used as a variable capacitance whereby applying a voltage changes the capacitance which effect the frequency of the tuning circuit
The equation used to calculate the resonant frequency of an LC circuit is: f 1 / (2(LC)), where f is the resonant frequency, L is the inductance of the circuit, and C is the capacitance of the circuit.
Ohm's Law relates voltage (V), current (I), and resistance (R) in a circuit but does not directly apply to capacitance. To find the total capacitance in a circuit, particularly in series or parallel configurations, you use specific formulas: for capacitors in series, the total capacitance (C_total) is given by 1/C_total = 1/C₁ + 1/C₂ + ... (for all capacitors), while for capacitors in parallel, C_total = C₁ + C₂ + ... . Thus, Ohm's Law is not used to calculate capacitance directly; instead, you use the principles specific to capacitors.
A Schering Bridge is a bridge circuit used for measuring an unknown electrical capacitance and its dissipation factor.
A preset capacitor, often referred to as a trimmer capacitor, is used in circuits to fine-tune capacitance values for specific applications. It allows for adjustments in capacitance, which can help in optimizing the performance of oscillators, filters, and tuning circuits. By providing a variable capacitance, it enables engineers to calibrate the circuit for desired frequency response or impedance matching. Once set, it can be left in place to maintain the desired circuit characteristics.
The symbol for farads is F, named after the physicist Michael Faraday. It is used to represent the unit of electrical capacitance in a circuit.
Gate capacitance is used in electronic circuits, particularly in field-effect transistors (FETs), to determine how quickly the gate can respond to changes in input signal voltage. It plays a crucial role in defining the switching speed and frequency response of the device, as it affects the charging and discharging times of the gate. Additionally, gate capacitance influences the overall input impedance of the circuit, which can impact signal integrity and power consumption. Understanding and managing gate capacitance is essential for optimizing circuit performance in high-speed applications.
In the Hay bridge, the capacitor is placed in series to improve the sensitivity of the measurement, allowing for a more accurate determination of capacitance by minimizing errors from stray capacitance. Conversely, in the Maxwell inductance-capacitance bridge, the capacitor is used in parallel to facilitate the comparison of inductance and capacitance directly, enabling a more straightforward calculation of circuit parameters. The differing configurations serve the specific needs of the measurement techniques employed in each bridge design.

Self capacitance refers to the capacitance between the touch sensor and the ground, while mutual capacitance refers to the capacitance between two different touch sensors. In capacitive touch technology, self capacitance is used for single-touch detection, while mutual capacitance is used for multi-touch detection.
