After some time the battery is disconnected and a dielectric slab of dielectric constant K ,
How does a capacitor charge a battery?
The net charge on the combination of the two plates of the capacitor is the same (zero) before and after charging so no charge has been "supplied" by the battery. The positive terminal of the battery pulls electrons off of the capacitor plate connected to it, making that plate positively charged.
How to calculate the total capacitance of a parallel circuit?
We can also define the total capacitance of the parallel circuit from the total stored coulomb charge using the Q = CV equation for charge on a capacitors plates. The total charge QT stored on all the plates equals the sum of the individual stored charges on each capacitor therefore,
What happens if a capacitor is connected together in parallel?
When capacitors are connected together in parallel the total or equivalent capacitance, CT in the circuit is equal to the sum of all the individual capacitors added together. This is because the top plate of capacitor, C1 is connected to the top plate of C2 which is connected to the top plate of C3 and so on.
Does a battery with 2 capacitors in parallel drain faster?
Hence I conclude, the battery with 2 capacitors in parallel will drain out faster than a battery with individual capacitors (considering we charge the capacitors many many times, causing the battery to loose the energy). Now does this all make sense or its just baloney? Now does this all make sense or it's just baloney? It's just baloney.
What happens if a capacitor is charged by a battery?
As E = V/d = and V is decreased; therefore, electric field decreases to 1/K times. (iii) Energy stored by the capacitor, u =Q 2 /2C. As Q = constant, C is increased, and so energy stored by capacitor decreases to 1/K times. A parallel plate capacitor is charged by a battery.
