A circuit is fed by two sources of different frequency and magnitudes 100 ∠0° V and 50 ∠30°V. The current in a particular branch is 10 ∠20° A. If the magnitudes of the sources are changed to 200 ∠0° V and 100 ∠0° V, the current in that branch should be

A circuit is fed by two sources of different frequency and magnitudes

1.	A circuit is fed by two sources of different frequency and magnitudes 100 ∠0° V and 50 ∠30°V. The current in a particular branch is 10 ∠20° A. If the magnitudes of the sources are changed to 200 ∠0° V and 100 ∠0° V, the current in that branch should be
A.	20 ∠20° A
B.	10 ∠20° A
C.	14.14 ∠20° A
D.	10 ∠- 20° A
Answer» B. 10 ∠20° A
