Question

For the questions on this page, a linear transformer is connected as shown below. Note that nothing is connected to the L2 side of the transformer. Assume l = 1.1/0° A, ZL1 = 316 0, ZL2 = 1900, and ZM = j27 0. M + + Is V Li L2 V2 Hint: When working with coupled inductors, start with the current through one inductor and mark its self-induced voltage and all mutually-induced voltages in any other inductors it is coupled to. Then, repeat for the current in each coupled inductor. Enter the magnitude of V2 (in V). Points possible: 3 Allowed attempts: 3 Retry penalty: 33.333% Submit Enter the magnitude of the current through L2 (in A). Points possible: 3 Allowed attempts: 3 Retry penalty: 33.333% Submit Enter the magnitude of V1 (in V). Points possible: 3 Allowed attempts: 3 Retry penalty: 33.333% Submit What is the transformer's coefficient of coupling (k)? Hint: Remember that ZL =jXL = jwL and ZM =jXM =jWM.
