$$\text { Figure } 14

Question

$$\text { Figure } 14 < 1$$
-In Figure 14-1, if the primary to secondary turns ratio is changed to 4:1 and a 1 kΩ load resistor is in the secondary, the secondary current equals ________.
A)30 mA 
B)240 mA 
C)120 mA 
D)480 mA

The secondary current is inversely proportional to the turns ratio. So, if the turns ratio is changed to 4:1, the secondary current will be 1/4 of the original value. The original secondary current was 120 mA, so the new secondary current will be 120 mA / 4 = 30 mA.
