Find the effective resistance in the diagram above

Assessment: JAMB UTME - Physics - 2008 Subject: Physics

Question 1 Report

Find the effective resistance in the diagram above

Answer Details
In the given diagram, resistors R1 and R2 are in parallel and their equivalent resistance can be calculated as follows: 1/Req = 1/R1 + 1/R2 1/Req = 1/6Ω + 1/6Ω = 2/6Ω Req = 3Ω Resistor R3 is in series with the combination of resistors R1 and R2. Thus, the total resistance of the circuit can be calculated as follows: Rtotal = R3 + Req Rtotal = 6Ω + 3Ω = 9Ω Therefore, the effective resistance in the given diagram is 9Ω. Option (D) is correct.
