A charged capacitor consisting of two parallel plates has an area and separate of 0.500 m2 and 9.00 mm respectively. If the electric field strength between the plates is 3.0 x 106 Vm-1, calculate the energy stored in the capacitor.

Cathode ray tubes (CRTs) used in old-style televisions have been replaced by modern LCD and LED screens. Part of the CRT included a set of accelerating plates separated by a distance of about 1.56 cm. If the potential difference across the plates was 24.0 kV, find the magnitude of the electric field (in V/m) in the region between the plates.   ????V/m

The electric field strength between two parallel conducting plates separated by 3.60 cm is 4.90 ✕ 104 V/m. a) What is the potential difference between the plates (in kV)? and b)The plate with the lowest potential is taken to be at zero volts. What is the potential (in V) 1.00 cm from that plate (and 2.60 cm from the other)?

An electron moving parallel to the x axis has an initial speed of 3.7 x 106 m/s at the origin. Its speed is reduced to 1.4 x 105 m/s at x = 2 cm. Calculate the electric potential difference 1. between the origin and x -= 2 cm. 2. A proton is released from rest in a uniform electric field whose magnitude is 5000 V/m. Through what potential difference will it have passed after moving 0.25 meters? How fast will it be going after it has travelled 0.25 meters?

The electric field Strength between two parallel conducting plates separated by 4.60 cm is 8.90*10^4 V/m. a) what is the potential difference in plates (in kV)  b) the plate with the lowest potential is taken to be at zero volts. What is the potential (in V) 2cm from that plate and 2.60cm from the other?

57. A spherical capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has a radius of ra = 12.0 cm , and the outer sphere has a radius of rb = 15.1 cm . A potential difference of 120 V is applied to the capacitor. What is the capacitance of the capacitor? What is the magnitude E1 of the electric field E at radius r= 12.8 cm , just outside the inner sphere? What is the magnitude of E at r= 14.7 cm , just inside the outer sphere?

What is the magnitude, in volts, of the maximum potential difference between two parallel conducting plates separated by 0.51 cm of air?

The voltage across a capacitor is given by the formula V=Q/C, where Q is usually called "the charge on the capacitor." Where is this charge in a capacitor? Does the capacitor really have a net charge?
