Transformers

A single-phase ideal transformer has a primary-to-secondary turns ratio of 4:1. If the secondary impedance is 2 $$Omega$$, the reflected impedance ($$Omega$$) as seen on the primary is most nearly:

A.  0.5
B.  2.0
C.  8.0
D.  32.0

An ideal transformer connects a 120-V, 60-Hz voltage source to a load. One terminal of the voltage source is grounded. The load is ungrounded. The circuit and transformer are operating normally (not in a fault condition). A person whose body is contacting ground is in proximity to the circuit. If the person touches the circuit, which point (A, B, C, or D) likely has the highest risk of resulting in a shock?

A.  Point A
B.  Point B
C.  Point C
D.  Point D
