Week 4:
Since the resistance overall would be reduced if there was a short in the secondary, the overall
power of the system would be greater. For example, say a transformer is designed to produce a
total of 10W between both primary and secondary (5V, 2.5

Xl=1257
Zt=1606
I=3.111mA
Vl=3.914V
Vr=3.111V
Z =1.254
I=3.111mA
Vl=3.914V
Vr=3.111V
Does this value equal the applied voltage, V T, of 5 V? Yes
How do these values compare to those originally calculated in Fig. 2136. The same

Unloaded Secondary: V3-4=12V
V4-5=12V
V3-5=12V
V1-2/V3-5=120/12=10
Does the full secondary voltage, V3-5, measure higher than its rated value?
Why? No. Since the turns ratio is 10:1, the secondary is 10 times lower than the primary.

For an inductor, the induced voltage, VL always _leads_ the current by 90 degrees
Inductive reactance is measured in
The angle between the generator voltage and its current is the _phase_ angle of
