Hi, why is it that when u integrate V wrt to Q u get (CV^2)/2 instead of QV since voltage across is constant?
Energy in capacitance refers to the amount of energy stored in a capacitor. A capacitor stores energy in the form of an electric field between two conductive plates, with the ability to release this energy when needed.
The energy stored in a capacitor can be calculated using the formula: E = 1/2 * C * V^2, where E is energy in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts.
The amount of energy stored in a capacitor can affect the performance of electronic devices by impacting the voltage and current levels. Capacitors are commonly used in electronic circuits to regulate voltage and provide temporary power when needed.
Yes, energy can be lost in capacitance due to various factors such as heat dissipation, leakage current, and resistance in the circuit. This is known as capacitor loss and can affect the overall efficiency of the circuit.
The energy stored in a capacitor can be increased by increasing the capacitance or the voltage across the capacitor. This can be achieved by using larger capacitors or connecting multiple capacitors in series or parallel, respectively.
