How to measure the charging voltage of a capacitor
capacitor
You CAN measure the capacitor voltage while charging and nit will be close to the capacitor voltage you see when the psu is disconnected. The internal capacitor resistance (ESR) will also cause voltage drop inside the capacitor due to resistive voltage drop (v = I x R) as for the wire.

An explanation of the charging and discharging curves for capacitors, time constants and how we can calculate capacitor charge, voltage and current....more.
Can you measure the voltage of a capacitor with using an …
My question is can I just use my oscilloscope to measure the voltage across a capacitor. Of course, you can. But there''s one thing to consider: There''s a circuit consisting of passive elements inside the scope''s probe. And, in your circuit, you are loading the capacitor with those elements. So the measurement can be affected by these …
5.19: Charging a Capacitor Through a Resistor
When the capacitor is fully charged, the current has dropped to zero, the potential difference across its plates is (V) (the EMF of the battery), and the energy stored in the …
How to Calculate the Charge on a Capacitor
The capacitance of a capacitor can be defined as the ratio of the amount of maximum charge (Q) that a capacitor can store to the applied voltage (V). V = C Q. Q = C V. So the amount of charge on a capacitor can be …
6 Methods of Capacitor Measurements (Guide, 2024)
And using an oscilloscope is of those many options for measuring the capacitance of a capacitor. The question is how? Well, the time constant is one of the amazing parameters of a capacitor that we can use for this method. The time taken by a capacitor to charge up to 63.2% of the given voltage source is called the capacitor time constant.

How to define the initial charge of a capacitor in SPICE
In the first hand, I have tried to charge the capacitors in a period of time. However, the charging current is very high and I am not sure whether the capacitor will be completely charged or not. Therefore, I am looking for a way to initiate the initial state of charge of a capacitor in SPICE.
How do capacitors work?
The maximum amount of charge you can store on the sphere is what we mean by its capacitance. The voltage (V), charge (Q), and capacitance are related by a very simple equation: C = Q/V. So the more charge you can store at a given voltage, without causing the air to break down and spark, the higher the capacitance.
