Voltage greater than capacitor
capacitance
$begingroup$ The sum of $V_C$ and $V_L$ can be greater than the supply voltage because the voltages are out of phase and don''t simply add together. If you''re claiming

The voltage across the capacitor can become greater than the source voltage when the circuit is at or near resonance. At resonance, the inductive reactance and capacitive
Can the output voltage of a circuit be larger than its input
The main risk of having a higher output voltage than input voltage in a circuit is the potential damage to the circuit components or external devices connected to the circuit.

Capacitor Charging
A rule of thumb is to charge a capacitor to a voltage below its voltage rating. If you feed voltage to a capacitor which is below the capacitor''s voltage rating, it will charge up to that voltage, safely, without any problem. If you feed voltage
Voltage Rating of a Capacitor
An alternating voltage of 500 volts (RMS) has a peak voltage of 707 volts, and a capacitor to which it is applied should have a working voltage of at least 750 volts. The capacitor should be

6 FAQs about [Voltage greater than capacitor]
Why does a Capacitor Read higher than the applied voltage?
A capacitor on a PSC induction motor which is wired in series with the start winding (and always in the circuit when running) will read higher than the applied voltage. This is due to the fact that although the cap is wired in series with the Start winding, it is also electrically connected across the Start and Run winding.
What is a characteristic of a capacitor?
Therefore we can state a particularly important characteristic of capacitors: The voltage across a capacitor cannot change instantaneously. (8.2.7) (8.2.7) The voltage across a capacitor cannot change instantaneously. This observation will be key to understanding the operation of capacitors in DC circuits.
How does voltage affect a capacitor?
The voltage across a capacitor leads is very analogous to water pressure in a pipe, as higher voltage leads to a higher flow rate of electrons (electric current) in a wire for a given electrical resistance, per Ohm's Law.
Why does a larger capacitor take longer to discharge than a smaller capacitor?
At any given voltage level, a larger capacitor stores more charge than a smaller capacitor, so, given the same discharge current (which, at any given voltage level, is determined by the value of the resistor), it would take longer to discharge a larger capacitor than a smaller capacitor.
What is the difference between capacitance and voltage?
C C is the capacitance in farads, Q Q is the charge in coulombs, V V is the voltage in volts. From Equation 8.2.2 8.2.2 we can see that, for any given voltage, the greater the capacitance, the greater the amount of charge that can be stored.
Why is the voltage of a capacitor important?
That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short. Expressed as a formula:
