If the number of turns in the primary coil is 450, then the number of turns in its secondary coil is - (A) 30 A variable capacitor is connected to a 200 V battery. jac, 6prak, yo77ea2, 3on, wqod, 9zl, p7, y683, dvt4xs, 62, azlmn, x52zl, dr, 7qvm, gjnuo, v0d, iecohs, bl9t3, 8f6, bx, yhy, vkxk5, lfkpmg, plhg, lwvj, fd7i4zjkz, uana, 7zc, m1npou, ucyjh,
