1. Two parallel plates of area 100cm^2 are given charges of equal magnitudes 8.9X10^-7 but opposite signs. The electric field within the dielectric material filling the space between the plates is 1.4X10^6 V/m.
(a) Calculate the dielectric constant of the material.
(b) Determine the magnitude of the charge induced on each dielectric surface.
2. You are asked to construct a capacitor having a capacitance near 1 nF and a breakdown potential in excess of 10000V. You think of using the sides of a tall Pyrex drinking glass as a dielectric, lining the inside and outside curved surfaces with aluminum foil to act as the plates. The glass is 15cm tall with an inner radius of 3.6cm and an outer radius of 3.8cm. What are the
(a) capacitance and
(b) breakdown potential of this capacitor?
When electros and holes are present in a semi-conductor, the presence of an electric field produced by an external voltage will cause this carries,which have changes of oposite sign, to move in opposite directions.
If the MOD-8 binary counter is driven by a 10 MHz input clock with a 5% duty cycle, what is the output frequency and duty cycle of the final stage
Let p represent the true portion of unauthorized uses of business websites in 2008 that came from inside the company. (a) Calculate a point estimate for p. (b) Set up the null and alternative hypothesis to test whether the value of p differs from ..
A Vs equals 1V source impedance 25ohms is connected by a switch to a 50-ohms lossless air transmission line 1 m long, terminated in a load of 30-ohms. At time t=0s, the switch is closed instantaneously to launch a step voltage down the line.
deposit Aluminum with a deposition rate of 100 nm/min. The substrate temperature is 300K. During the deposition, your chamber has an air leak that provides a residual O2 partial pressure of 10-6 Torr.
To discharge a capacitor of 1mF charged with a voltage of 1 volt we connect it, at time t=0, with a resistor of R-ohm. When we measure the voltage in the resistor we find it to be v_R (t)=e^(-t) u(t). Determine the resistance R.
A gas occupying a volume of 25 ft3 weights 3.5 lbs on the moon, where the acceleration of gravity is 5.47 ft/s2. Determine its weight, in lbf, and density, in lb/ft3, on Mars, where g= 12.86 ft/s2.
According to the Nyquist sampling theorem, faithful reconstruction of an analog signal with a bandwidth of 29 kHz would require a sampling frequency of at least. what is the decimal equivalent of the following binary coded decimal number.
In the question below only focus on the parameter or parameters that are relevant to the particular property you are being asked about in the particular question. If you need to constrain a parameter to satisfy the stated criterion.
An inverting amplifier is configured for a gain of -(6/4) using an opamp that has a 2mV internal offset voltage. (You may consider the opamp ideal otherwise). For what input voltage the output of the amplifier will be zero.
using a slotted line the following results were obtained distance of first minimum from the load 4 cm distance of
