How do you calculate the maximum voltage across a capacitor in an L,R,C series circuit?
Voltage across a capacitor refers to the potential difference between the two plates of the capacitor. It is a measure of the electrical energy stored in the capacitor and is measured in volts.
The voltage across a capacitor can be calculated using the formula V = Q/C, where V is the voltage, Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
In a DC circuit, the voltage across a capacitor remains constant once the capacitor is fully charged. This is because a capacitor acts as an open circuit in a DC circuit once it is fully charged.
In an AC circuit, the voltage across a capacitor varies with time. It follows a sinusoidal waveform, where the voltage increases as the capacitor charges and decreases as it discharges.
The dielectric material of a capacitor can affect the voltage across it by changing the capacitance of the capacitor. A higher dielectric constant material will result in a higher capacitance and therefore a higher voltage across the capacitor when the same amount of charge is stored.
