In a certain transformer, the input power to the primary is 120 W. If 8.5 W are lost to the winding resistance, what is the output power to the load, neglecting any other issues?
-
When a 6 V battery is connected across the primary of a transformer with a turns ratio of 8, the secondary voltage is
-
What is the coefficient of coupling for a transformer in which 4% of the total flux generated in the primary does not pass through the secondary?
-
A transformer has a 1:6 turns ratio and a secondary coil load resistance of 470
. The load resistance as seen by the source is
