A source of 100 V 0° drives a branch Z1=60, in series with the parallel branch Z2=10+j40, , as shown. Terminals a and b are the open terminals across Z2. Find the magnitude of the Thevenin voltage.
- 40.7 V
- 74.4 V
- 51.1 V
- 100 V
Answer
C. 51.1 V
Solution
VTh=VZ2/Z1+Z2=100 V·10+j40, /70+j40, =51.1 46.2° V.
