Question: An uncharged nonconductive hollow sphere of radius16.0cm surrounds a17.0µC charge located at the origin of a cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along thezaxis, and a hole is drilled in the sphere. Calculate the electric flux through the hole.
measure it and calculate the frequency to which the signal generator must be set. when using the slotted line
using a slotted line the voltage on a lossless transmission line was found to have a maximum magnitude of 1.5 v and a
The photoelectric threshold wavelength for Tungsten is 2300 Å. Find the energy in eV of the emitted electrons from the surface by ultraviolet light of wavelength 1800 Å.
Show how to wire the two gauges and two fixed 150 W resistors into the bridge circuit to provide temperature compensation, using the graphs given on the right. The plastic tube has an outer diameter of 3 cm and an inner diameter of 2.3 cm.
A 2000 KVA, 4800-600V, 60 Hz, core type transformer operating at no load in the step down mode draws a magnetizing current equal to 2 percent rated current. The core has a mean length of 3.15 m, and is operating at a flux density of 1.55 T.
A 1 kHz sine wave signal with a power level -10 dBm is applied to the input of the amplifier. What is the power at the amplifier output?
The diameter of no.12 Copper wire is 0.081in. The max. safe currentit can carry is 20 A. At this current, what is the drift velocityof the electrons (the number of electrons carries on cubiccentimeter of copper is 8.5 x 1022.)
A charged particle starts from rest at the origin of coordinates in a region where there is a uniform electric field E parallel to the x-axis, and a uniform magnetic flux density B parallel to the z-axis. Show that the coordinates of the particle ..
The tungsten filament of an incandescent lamp had aresistance of 7 ohms at a room temperature of 24oC. When it is connected to the electric source the resistance rises to 96ohms. Compute the operating temperature. The inferred zero fortungsten is ..
The National Electrical Code specifies, among otherthings, values for the minimum allowable cross-sectional area ofconductors for a given voltage and allowable total length ofcircuits depending on the diameter of conductor used.
design a 3-bit synchronous counter (using only D-flip flops and NAND gates) that produces the sequence 000, 010, 011, 001, 101, 100, 000, etc. whenever the single input is 1. The counter retains its current value whenever the input bit is 0.
A small ac motor, draws 100 VA from its 120-Vrms, 60 Hz ac source and consumes 50 W. Find the rms current the motor draws from the supply.
