Since V is directly proportional to electric field so as V' decreases (1\2) (1+K) times the electric field strength also decreases by the same amount. This is the required answer. A spherical capacitor has charges + Q and - Q on its inner and outer conductors. Find the electric potential energy stored in the capacitor?
For finding the capacitance of the capacitor having continuously varying dielectric, we would have to perform integration over whole variation. The Potential Difference between AB is 6 V. Considering the branch AB, the capacitors 2 μ F and 5 μ F are in parallel and their equivalent capacitance = 2 + 5 = 7 μ F.
Solution: After a long period of time, the accumulated charge on the capacitor's plates will produce a voltage across the capacitor that is equal to the voltage across the power supply. At that point, there will no longer be current in the circuit.
U is the electric potential energy (in J) stored in the capacitor’s electric field. This energy stored in the capacitor’s electric field becomes essential for powering various applications, from smartphones to electric cars (EVs). Dielectrics are materials with very high electrical resistivity, making them excellent insulators.
