What is breakdown voltage? - Physics Stack Exchange 3 There is no material you could use as a dielectric between the plates of a capacitor which will have a higher breakdown voltage than a vacuum Therefore, the maximum voltage you can place across a capacitor will be the breakdown voltage of its dielectric and this "Vmax" will always be lower than the Vmax for the vacuum case
Understanding Breakdown Voltage of PN Junctions Hi, Being a computer science and eng first year student, just trying to understand one artical regarding Breakdown voltage of the pn junction Could anybody explain me, which diode out of the following have higher breakdown voltage if they have same design parameters such as doping and thickness
Breakdown voltage of a dielectric - Physics Stack Exchange 2 I know that a capacitor with a dielectric can operate normally up till a certain voltage (AFAIK called breakdown voltage) which depends on the strength of the dielectric placed between the plates After this voltage, the circuit becomes short and current flows between the plates and thus the capacitor breaks down
electricity - Why does the breakdown voltage increase when the . . . the initiation of breakdown depends on the availability of ultraviolet photons by placing the electrodes ever closer together, it gets hard to get any UV photons into the gap to trigger the discharge, and the breakdown voltage rises
What exactly is breakdown voltage of air? - Physics Stack Exchange There is no such thing as "a breakdown voltage" What is relevant is the electric field at which a cascade develops in a small volume element Since the electric field depends on the shape of the electrodes, one can cause gas discharges around sharp tips and edges at a lower voltage than for perfectly flat or spherical electrodes Indeed, it is hard to get anywhere close to the max breakdown
Estimating the field strength of dielectric breakdown of air from a . . . Any deviation from that will likely reduce the breakdown voltage: Say you have a dust particle - it will have an irregular shape with sharp edges that will locally increase the electric field - your avalanche can start there Similar thing with water droplets or maybe even random pressure fluctuations
What Is the Breakdown Voltage of the Capacitor Combination? The discussion focuses on calculating the breakdown voltage of a capacitor combination, where each capacitor has a breakdown voltage of 15 0 V The user initially assumes that the voltage across the parallel capacitors is the same and attempts to apply the formula for capacitance in series and parallel configurations However, mistakes are identified in the calculations, particularly in the
condensed matter - Why is collector-emitter breakdown voltage (open . . . 0 I need to understand why the collector base breakdown voltage is greater than collector emitter breakdown voltage Can it be analyzed from the energy band diagram so as to remember it mnemotechnically? Most of the sources analyze it from a mathematical point of view only, I need to understand the mechanism so to remember it intuitively
Breakdown Voltage of PN Junctions: P+-N vs. N+-P Hiya, Being a computer science and eng first year student, just trying to understand one artical regarding Breakdown voltage of a pn junction Could anybody explain me, which diode out of the following have higher breakdown voltage if they have same design parameters such as doping and
