Four 18W lamps are connected in parallel across 6V. Draw circuit. What is the current though each lamp? What is the resistance of each? What is the effective resistance of the combined four lamps?
A collimated light beam from a helium-neon laser at 632.8 nm wavelength impinges on a dielectric film of refractive index of 2.0 at an angle of 75 degrees to normal, with a polarization at 45 degrees to the plane of incidence.
A 3-phase 230 V, 9 kVA, 0.9 PF (lagging) load is supplied by 10 kVA, 1330/230 V, 60 Hz three-phase transformer connected in Y-?. The equivalent impedance of transformer referred to the low-voltage side is 0.12 + j0.25.
Design a circuit that can perform BCD addition on two decimal digits. You don't have to design any of the major components you may use (such as adders, comparators, etc.). Assume all those components are available.
A 240kW 500V 1750 r/min separately excited dc generator has an overall efiiciency of 94%. The shunt field resistance is 60 ohms and the rated current is 5A. The I^2 R loss in the armature is 0.023 pu.
given a "black box" with two terminals. You play around with the box for awhileand make the following observations: (i) The output voltage from the box is sinusoidal. (ii) The peak magnitude of the open-circuit voltage at the terminals is 5 V.
A DC motor is driving a load given by TL = 3 + 0.02ωLNm , where ωL is the speed in rad/sec. The armature resistance of the motor, Ra = 2Ω . The machine constants at rated flux density, kE=kT=0.4 (inSIunits).
Make sure to mark significant points in your figure (amplitude, offset, time, etc.). How could a device be modified to work as an electro-optic phase modulator? If we apply signal V, what is the range of phase shifts induced by this modulator.
A 5.00 cm thick layer of oil is sandwiched between 1.00 cm thick sheet of glass and a 2.00 cm thick sheet of polystyrene plastic. How long (in nano-seconds) does it take for light incident perpendicular to the glass to pass through this 8.00 cm th..
A single-phase, 100-kVA, 1000:100-V, 60-Hz transformer has the following test results: Open-circuit test (FIV side open): 100 V, 6 A, 400 W Short-circuit test (LV side shorted): 50 V, 100 A, 1800 W 1)Determine the voltage regulation at 75% of the rat..
When the two windings are connected to a a.c supply of 50hz, the field current is 0.1A, the armature current is 100A and the phase difference between them is 60 degree. calculate the average torque and maximum torque.
A 15μF capacitor is connected to a 50 V battery andbecomes fully charged. The battery is removed and a slab ofdielectric that completely fills the space between the plates isinserted. If the dielectric has a dielectric constant of 5.0,
Given the following: i) The column vectors: X1=[2 4 6]'; X2=[4 5 7]'; X3=[7 8 3]' % Note the above are column vectors (% In Matlab, ' means Transpose). ii) The matrix: A=[X1 X2 X3]. 1)B=A'; % In Matlab, ' means Transpose. This defines B.
