An LR circuit having L = 4.0 H, R = 1.0 Omega and epsilon = 6.0 V is switched on at t = 0 . find the power dissipated in joule heating at t = 4.0 s .

If at t^oC , K_w = 10^-14 , then pH of pure water at t^oC will be a) 4 b) 6 c) 7 d) 12

Normals are drawn to the parabola yz =4ax at points A,B.C whose parameters are t1 12 andt, respectively If these normals enclose a triangle PQR, then prove that ? íts area is-' (11-4) (4-6) (4-11) (t1 +?t3)2 Also prove that ? PQR = ? ABC (11+12+13)2 12) (2

A current of 4 A flows in a coil when connected to a 12 V dc source. If the same coil is connected to a 12 V, 50 rad s^(-1) ac source, a current of 2.4 A flows of the coil in the circuit. The power developed in the circuit of a 2500 (mu)F capacitor that is connected in series with the coil is
