Peak voltage across a capacitor refers to the maximum voltage that occurs across the capacitor during its charging and discharging cycles.
The peak voltage across a capacitor can be calculated using the formula Vp = Vs + (V0 - Vs)e^(-t/RC), where Vp is the peak voltage, Vs is the steady-state voltage, V0 is the initial voltage, t is the time, R is the resistance, and C is the capacitance.
The factors that affect peak voltage across a capacitor include the capacitance, resistance, and the time constant (RC) of the circuit.
The peak voltage across a capacitor decreases over time as the capacitor charges and discharges, eventually reaching a steady-state voltage.
Peak voltage across a capacitor is important to consider because it determines the maximum voltage that the capacitor can handle without breaking down. This is especially important in high voltage applications to prevent damage to the capacitor and other components in the circuit.
