A single-phase transformer has a voltage ratio of 6:1 and the h.v.winding is supplied at 540V.
The secondary winding gives a full load current of 30A at a power factor of 0.8 lagging. Neglecting losses,
Find
(a) The rating of the transformer,
(b) The power supplied to the load,
(c) The primary current

In the mass spectrograph, two positively charged ions having the similar velocity pass through a slit and enter a uniform magnetic field at right angles to their initial velocities
A highly polished metal surface is coated with a colloidal aqueous dispersion of P.T.F.E. it is force dried and sintered, until a continuous film is formed. These capacitors can wi
EXplain fraunhofer diffraction due to a single slit and deduce the position of maxima and minima and find their relative intensities
Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength. Work function W = hγ o = h C / λ 0 λ 0 = h C / W = 6.626 X 10 -34 X 3 X 10 8
Water flows through a right angle valve at the rate of 1000 lbm/s as shown in the figure. The pressure just upstream of the valve is 90 psi and the pressure drop across the valve i
When a string under tension is set into vibration, transverse harmonic rays propagate along its length. When the size of string is same, reflected rays will also exist. The operati
Action and reaction in pushing forces Forces work in pairs. If you push against a wall, the wall pushes with equivalent force back against you. Secure two kitchen spring balanc
Why do magnetic field lines contract longitudinally and exert a lateral pressure?
The molecular theory of magnetism was given by Weber and modified later by Ewing. According to that theory - Each molecule of a substance is a complete magnet in itself. Though,
