1. A 200-nF capacitor is charged to 1000 V, and then connected across (in parallel) an initially uncharged 100-nF capacitors. What is the change in energy of the 200-nF capacitor? (Step by step solution)

A cathode ray tube (CRT) is a device that produces a focused beam of electrons in a vacuum. The electrons strike a phosphor-coated glass screen at the end of the tube, which produces a bright spot of light. The position of the bright spot of light on the screen can be adjusted by deflecting the electrons with electrical fields, magnetic fields, or both. Although the CRT tube was once commonly found in televisions, computer displays, and oscilloscopes, newer appliances use a liquid crystal display (LCD) or plasma screen. You still may come across a CRT in your study of science. Consider a CRT with an electron beam average current of 31.00 μA. How many electrons strike the screen every minute?

1. An evacuated tube uses an accelerating voltage of 45 kV to accelerate electrons to hit a copper plate and produce x-rays. (a) Calculate the work done in accelerating a single electron through this potential difference. W = J (b) Calculate the change in PE of a single electron through this potential difference. ΔΡΕ J

(#220983) {Electric Potential} The spark plugs in an automobile engine produce an electrical spark to ignite the fuel in the engine's combustion chamber. The spark is produced by applying a large voltage across the two electrodes (i.e., small exposed pieces of metal) that are separated by a small air-filled gap. When the electric field in the gap exceeds the electrical breakdown threshold for air, a spark will form across the gap. The gap thickness in most spark plugs run between 0.6 mm and 1.8 mm, and the breakdown threshold for air is 3.0 × 106. Calculate the minimum voltage that must be supplied to the spark plug to guarantee ignition for this full range of gap sizes. (Hint: think about whether a smaller gap or a larger gap will require more voltage to spark, and you want to guarantee that all gap sizes will fire with your "minimum" voltage) m Enter answer here Air Gap Electrodes Image adapted from publicdomainvectors.com Please enter a numerical answer below.
