The electric field between square the plates of a parallel-plate capacitor has magnitude E. The potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. The magnitude of the electric field between the plates is now equal to 4E 2E E/2 E A 6.0-mu F capacitor charged to 50 V and a 4.0-Mu F capacitor charged to 30 V are connected to each other, with the two positive plates connected and the two negative plates connected. What is the potential difference across the 6.0-Mu F capacitor at equilibrium 42.0 V 16.4 V 18.2 V 21.8 V The equivalent capacitance of the circuit shown below is: 1.0C 0.5C 1.5C 2.0CExplanation / Answer
We know that the field and voltage drop in a capacitor are related as
V = E * d
Where V is the voltage, d the seperation and E the electric field.
As the distance is doubled the field will get half to keep the volatge constant.
C) E/2
