A battery of voltage ΔVbat is connected to a parallel plate capacitor as shown above. Then, without breaking any connections, the separation between the capacitor plates is increased from d to 2d. How does the potential difference across the capacitor, ΔVC, change as the separation increases? It's impossible to know for sure. It increases to double its original value. It decreases to half its original value. It stays the same.
1 There is a parallel-plate capacitor consists of two circular metal disks of radius R = 0.40 m separated by an insulating medium of permittivity (Epsilon)= 8.0(Epsilon)0(Naught) with thickness d = 0.20 mm. From Q = CV , a current I = dQ/dt coming on a wire into the positive terminal implies a changing voltage difference between the plates, dV/dt. The dielectric has a poor conductivity σ = 0.25 Ω·m, and is driven with an AC signal at frequency f = 400 MHz. What is the ratio of conduction current magnitude to displacement current magnitude through the capacitor?
Mr X and Mr Y are two friends. One day they were walking on the street and saw that a man in a strange dress had shown many magical activities. He introduced a crystal that turned on the LED light by giving pressure on it. Everyone was surprised by that activities. But Mr Y said that this crystal is a piezoelectric transducer and is also known as a self-transducer. However, it can't generate high voltage. Could you explain what the main reasons for generating the low output voltage are?

Q14 The circuit shown in Figure 19.61 consists of two flashlight batteries, a large air-gap capacitor, and Nichrome wire. The circuit is allowed to run long enough that the capacitor is fully charged with +Q and -Q on the plates.
