A single-phase transformer has 480 turns on the primary and 90 turns on the secondary. The mean length of the flux path in the core is 1.8 m and the joints are equivalent to an airgap of 0.1 mm. The value of the magnetic field strength for 1.1 T in the core is 400 A/m, the corresponding core loss is 1.7 W/kg at 50 Hz and the density of the core is 7800 kg/m3.
If the maximum value of the flux density is to be 1.1 T when a p.d. of 2200 V at 50 Hz is applied to the primary, calculate:
(a) the cross-sectional area of the core;
(b) the secondary voltage on no load;
(c) the primary current and power factor on no load.
How to solve electrical circuits analytically using different theorems and simulate them on Multisim.
Do this using for loops. For your first prompt you will enter the number N of integers that will follow, then you will be prompted for each integer. Compute the sum and average and provide the output. Do it 3 times using the Matlab, Python, C++
Problem 1. In a city full of sunshine there are a number of people. They can either drive their cars (to work or elsewhere), which can cause pollution and traffic jams, or they can ride bicycles (which is not problematic, given that in that city it a..
Assuming that the maximum depth of Kraken Mare is less than 400 meters, how much pressure in atmospheres must the submersible be designed to withstand Assumer the surface pressure on Titan is 17 kilopascals, the surface temperature is 94 kelvin
An infinitely long line charge (Pl= 21 PI nC/m) lies along the Z-axis. An infinte area sheet charge PS= 3nC/m^2 lies in the X-Z plane at a distance Y =10 m. a) Using Gauss' law find the field E due to the line charge.
Other combinations of R, L, and C have behaviors similar to that of the series resonant circuit. For example, consider the circuit shown in Figure. Derive an expression for the resonant frequency of this circuit.
find the complete functions, p(t) and w(t) supplied by the element, not just a number, and graph p(t) and w(t). Choose appropriate intervals of time for your graphs. Assume that both v(t) and i(t) are zero for t
Many reactors are sited next to large bodies of water so that they can use the water for cooling. Consider a reactor where the intake water is at 18° C. State regulations limit the temperature of the output water to 30° C so as to not harm aquatic..
Obtain a primitive flow table for an asynchronous circuit with two inputs, x1 and x2, and two outputs z1,z2 that operates according to the following specs: a) when x1x2 = 00, the output z1z2 = 00
Finding peak amplitude, frequency, and spectrum shape, b. A signal generator outputs a unipolar square wave with a period of 0.50 ms and an amplitude of 2.0 V. The output of the generator is passed through an ideal band pass filter that has a pass..
A pn-junction is uniformly doped and has dopant concentration of NA = 4 x10^16 cm-3 in the p-region at 300K. AT zero bias, 20% of the total space charge region (W) is extended in the p-region. Calculate Vbi, ND, W, xn and xp.
