Uniform Alternate Electric Field
Suppose a particle moves under a uniform (i.e. independent of space co-ordinates) but alternating electric field E given by,
E = E0 sin ω t = ( E0 i) sin ω t (i)where, E0 is amplitude and ω is angular frequency of oscillation. We define the direction of electric field as X-axis.The equation of motion of the particle of mass m and charge q in this field is, Integrating, we find where constant of integration c1 is set by initial condition: at t = 0, when E = 0, let v = v0. Hence, we get Integrating once again, we find where constant of integration r0 is the initial position of the particle; at t = 0, r = r0.We can always put r0 = 0; let us also take v0 = 0. Further, if E0 = E0 i, we have The particle moves along X-axis with time dependent speed vx (t). The average speed of the particle during a cycle is, vx is called the drift velocity of the particle. The displacement of the particle during one complete cycle, i.e. in time T, The graph between x and t is obtained by superposing the sine curve and the straight line,x = x1 + x2 If v0 ≠ 0, the particle may continue to move along y and z directions with constant initial velocities voy and voz. Simultaneously, it is drifted towards X-axis by a fixed distance per cycle, viz.
The steam that leaves the super-heater is expanded from 130bar at 535°C to 25.2bar at 310°C in a high pressure turbine. The steam from the exit of the HP turbine is reheated to 535
Mash stitch welding An overlap of about 1.15 mm is kept and then the plates are squeezed flash by application of pressure at hot condition. Mash stitch welding is used in the
what are the practical applications and use of finding uniform distributed load, concentrated point load, inclined point load, roller supported beam.
Need of a spectrophotometer: The specific instructions will differ with other models, but the principles remain. 1. The instrument must have been warm for at least 15 min.
