Question

Determine voltage appearing across terminals y-z, if a dc voltage of 100v is applied across x-y terminals

Answer 1

Answer:

Converting delta network to star network

Current, i=\frac{100}{1+3.846+0.77+2}=\frac{100}{7.616}=13.13Ai=

1+3.846+0.77+2

100

=

7.616

100

=13.13A

Y_{z}^{N},V_{z}=-13.13\times (2+0.77)Y

z

N

,V

z

=−13.13×(2+0.77) =-36.37V=−36.37V
