Calculate the maximum DC voltage available from a half wave rectifier Shown . Also find the reading of the milli ammeter.  Solution:- Turn ratio of transformer = 20:1 Number of turns in primary binding = 20 Number of turns in secondary binding = 1 Mains voltage supply(1/p) Vp = 220 v From the Transformer ratio formula Np/Ns = Vp/Vs 20/1 = 220/ Vs Vs = 220/20 = 11V Vrms = Vm/√2  => Vm = Vrms √2 => Vm = 11 √2 Vm = 15.5563 v Vdc =  2Vm /π Vdc = 2×15.5563/π = 9.90V I = V/R => 9.90/1×1000 I = 9.90mA

kinematics 12th

  A body is thrown vertically upwards with an initial velocity u reaches the maximum height in 6s. The ratio of the distance traveled by the body in first second to seventh second is   Initial velocity u = g×t = 9.8 ×6 = 58.8 m/s   distance S 1 travelled in first second is calculated using " S = u ×t - (1/2)×g×t 2  ", using u = 58.8 m/s, and t = 1 s;   S 1  = 58.8 ×1 -(1/2) ×9.8 ×1 ×= 53.9 m   Since the paticle reaches maximum height in 6 s, at 7th second travel, its initial velocity is zero.   hence distance S 7  travelled in 7th second = (1/2) ×9.8 ×1 ×1 = 4.9 m   hence the ratio S 1  / S 7  = 53.9 / 4.9 = 11
