Q1:

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

ANS:A - 20 ∠20° A
