If A1 = 4A, A2 = 2A and A3 = 2A, what would A4 read? if connected in parallel.

Answer 1

If A1, A2, and A3 are connected in parallel, then their equivalent resistance would be:

1/Req = 1/A1 + 1/A2 + 1/A3

1/Req = 1/4A + 1/2A + 1/2A

1/Req = 1/A

Therefore, A4 would also be 2A when connected in parallel with A1, A2, and A3.
