What happens when a capacitor connected across a battery for a long time?

∙ 14y ago
For a long time, The capacitor will be charged to the voltage of the DC battery, the positive side of the capacitor touching the positive terminal of the battery. Not much DC current will conduct, except for some tiny leakage current due to imperfection of the cap. The battery will be drained eventually.

What is the voltage across six 1.5 V batteries when they are connected A in a series B in parallel?
a 9V b 1.5V
How is a violin and friction connected?
When played with a bow, the friction of the bow (horse hair, or a synthetic material, usually rubbed with a sticky resin of some type) being pushed or pulled across the strings causes the string to vibrate, and therefore, for sound to be created.
What beatles song starts with across?
Across The Universe
When was Drums Across the River created?
Drums Across the River was created in 1954-06.
When was Across a Crowded Room created?
Across a Crowded Room was created in 1984-10.
IF capacitor that has been connected across a battery for comparatively long time becomes?
If the capacitor isn't punctured or failed, then it becomes charged to the voltage of the battery almost immediately after it's connected to it, and stays that way.
A resistor and a capacitor are connected in parallel across a 120 v dc source determine the voltages across the resistor and the capacitor?
Since they're connected in parallel directly across the source, the voltages across both componentsare equal, and are equal to the source, i.e. 120 v DC.
What happens to the charge if you double the voltage across a capacitor?
In order to double the voltage across a capacitor, you need to stuff twice as much charge into it.
What happens when lagging Power Factor changes to leading PF?
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
What happens to the current in a circuit as a capacitor charges?
What happens to the current in a circuit as a capacitor charges depends on the circuit. As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as the voltage source.
How a trimmer capacitor use?
A trimmer capacitor is a semi-adjustable capacitor placed across a variable tuning capacitor and pre-set to allow the main capacitor to track correctly with another variable capacitor on the same shaft. The adjustment takes out any differences introduced by the connected circuit.
Why does each plate receive charge of exactly same magnitude?
the plates of capacitor are connected to the same battery so same potential difference will develop across the plates of capacitors, as a result charges of same magnitude will be stored, as the charges are being supplied by the same battery.
What is the meaning of electronic capacitor?
A capacitor could be two parallel plates close together but unconnected, and then the plates are connected to either side of a battery. Current flowing causes charge to build up on the plates, positive on one plate and negative on the other, until the voltage across the capacitor is equal to the battery voltage. The amount of charge that has flowed in, divided by the voltage, is called the capacitance, measured in Farads.If the battery was one volt, and the charge was one coulomb (i.e. one amp for one second), then the capacitor has a capacitance of one Farad.Usually capacitors are measured in microfarads or picofarads.
What happens if you put a inductor in parallel with a capacitor?
both of these components connected in parallel will cause an oscillation of energy, meaning the capacitor will charge and then discharge through the inductor , which will then build up a magnetic field and discharge through the cap again , and this oscillation will go on for quite some time and then finally die out , and also if a multimeter is place across the cap it should short out , because it's as if you have connected a piece of wire right across it ...
Can a wire connected across a battery's terminal produce current?
Yes
What are the initial conditions for voltage across the capacitor and current through the inductor in the dc steady state?
The initial condition is the voltage and/or current existing at the time a mathematical solution begins. Example: what happens when a resistor is connected across a capacitor? well, you say that at t=0 the resistor is connected, then after that the voltage across the capacitor is v0.exp(-t/RC), where v0 is the starting voltage, t is the time, R is the resistance and C is the capacitance. This simple solution needs only one initial condition which is the starting voltage v0 across the capacitor. Linear differential equations are common in electrical engineering and a complete solution of one (such as the example) always requires one or more initial conditions.
