Calculate the equivalent resistance between A and B.
A. 60 ohm
B. 15 ohm
C. 12 ohm
D. 48 ohm
Answer:C
Calculate the equivalent resistance between A and B.
A. 60 ohm B. 15 ohm C. 12 ohm D. 48 ohm
Explanation: 5 ohm and 15 ohm are connected in series to give 20 ohm.10ohm and 20 ohm are connected in series to give 30 ohm. Now both equivalent resistances (20ohm and 30 ohm) are in parallel to give equivalent resistance 20*30/(20+30) = 12 ohm.
