Question

A charged capacitor and an inductor are connected at time t = 0. In terms of the period T of the resulting oscillations, what is the first later time at which the following reach a maximum? UB 0.25 times T the magnetic flux through the inductor 0.50 times times T di/dt 0.75 times T the emf of the inductor 0.25 times times T A transformer has 400 primary turns and 10 secondary turns. If Vp is 114 V (rms), what is Vs, assuming an open circuit? 2.85 V If the secondary is now connected to a resistive load of 23 Ohm, what is the current in the primary? .1239 times A What then is the current in the secondary? 0.0031 times A

Explanation / Answer

   we are given that    Np = 400    Ns = 10    Vs / Vp =Ns / Np                = Ip / Is    if R is the resistive load then theequivalent resistance of the secondary circuit is    Req = (Ns /Np)2 R    R = 23    solve for current in primary andsecondary
