Also asked, What voltage can I use to charge a capacitor? You can charge a **capacitor **to any DC **voltage **not exceeding its rating, within permissible environmental conditions. Only thing to remember is the **voltage **source must be DC or rectified DC if AC source is used. The charging circuit and source must have capability to supply necessary current safely 307 views Libu Sigat , Study electronics at school ^{[9]}

Herein, Which is faster to discharge or to charge a capacitor? **To **charge a **capacitor **faster, you need **to **supply more charging current. A **capacitor **will charge at a linear rate (dv/dt = a constant) when charged by a current source. A constant voltage supply can also be used through a resistor, but in this case, charging **to **the supply voltage will be exponential, with a time constant (T) equal **to **R*C (in seconds, where R is in ohms and C is in Farads). ^{[9]}

Simply so, Can We give the desired charge to a capacitor? You can give any amount of **charge to capacitor **so long as its rated voltage **is **not exceeded. Q=CV decides **the **maximum **charge **on **capacitor **at its maximum permissible voltage. Exceeding this voltage can lead **to **deterioration or damage of **capacitor **on account of breakdown of dielectric. Of course you can. ^{[4]}

## What voltage can I use to charge a capacitor?

Subsequently, Does voltage matter when charging a capacitor? The **voltage **rating is only the maximum **voltage **that **a capacitor **should be exposed **to**, not the **voltage **that the **capacitor **will **charge **up **to**. **A capacitor **will only **charge to a **specific **voltage **level if fed that level of **voltage **from **a **DC power source. Keep in mind that **a **good rule for choosing the **voltage **ratings for capacitors is not **to **choose the exact **voltage **rating that the power supply will supply it. ^{[9]}

Besides, How do you calculate the voltage of a capacitor?

- A parallel plate capacitor has square plates of side 5 cm and separated by a distance of 1 mm. ( a) Calculate the capacitance of this capacitor. (…
- = 221.2 ×10−13 F.
- C = 22 . 12 ×10−12 F = 22 .12 pF.
- = 22 . 12 ×10−12 ×10 = 221.2 ×10−12 C = 221.2 pC.

## Which is faster to discharge or to charge a capacitor?

Similarly one may ask, Why do charge and discharge curves follow the same time frame? While charging , at the end of one time constant , **capacitor **gets charged **to **67% of applied voltage, and after 5 time constants, the voltage on **capacitor is **99%. Exactly reverse happens while discharging from charged position. So **charge **and **discharge **curves follow same time frame. ^{[9]}

Also to know is, Do electrolytic capacitors discharge faster than electrostatic capacitors? Electrolytic capacitors **discharge faster **than electrostatic capacitors, and again within electrostatic capacitors, it will depend on the dielectric and manufacturing processes. Same goes for electrolytics of different kinds. However, electrostatic capacitors have really extremely long self **discharge **times, and may remain charged for even years. ^{[6]}

Then, Does a capacitor increase voltage when current is high? In general it doesn’t. The voltage on the capacitor changes faster when there’s more current flowing in (or out), and slower when the capacitor is bigger: rate = I C volts per second. Here I is the current and C is the capacitance. ^{[9]}

Herein, What is the speed of charging and discharging capacitor? The speed of charging and discharging **a capacitor **depends on the circuit used.If you **charge **through **a **resistor and **discharge **through **a **short circuit-the **discharge **will be much **faster **than the **charge**. If you see the **charge discharge **curve of **capacitor**, it follows **a **fixed pattern. ^{[9]}

## Can We give the desired charge to a capacitor?

Beside above, Why do capacitors need to be installed close to the load? **The **closer **a capacitor **is installed **to the **actual inductive load itself, **the **more beneficial. ^{[4]}

Subsequently, Where do capacitors get their charges from? **The **somewhat surprising answer **to **this is that **the **charges come from inside **the capacitor **itself. What happens when you **charge a capacitor **is that one plate becomes more positive and **the **other plate becomes more negative, by **the **same amount in each case. So **we **need **to **consider each plate separately. ^{[4]}

Then, How does a capacitor charge the battery of a car? 1) **The capacitor **must begin by being charged up **to a **voltage greater than **the **battery voltage. It will then deliver **charge to the **battery until it has moved enough **charge **that its voltage falls **to the **battery voltage. Then no more **charge **will be delivered **to the **battery. ^{[4]}

Beside above, What is the maximum amount of charge a capacitor can give? You **can give **any amount of **charge to capacitor **so long as its rated voltage is not exceeded. Q=CV decides **the **maximum **charge **on **capacitor **at its maximum permissible voltage. Exceeding this voltage **can **lead **to **deterioration or damage of **capacitor **on account of breakdown of dielectric. ^{[4]}
