Question

What are the values of two resistances which when connected in parallel give an equivalent resistance of 2 ohms and when connected in series is equivalent to 9 ohms?

Answer 1

Answer:

1. The values of two resistors are R1=(6±0.3)kΩ and R2=(10±0.2)kΩ. The percentage error in the equivalent resistance when they are connected in parallel is. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams
2. Two resistances when connected in series, resultant value is 9 ohms. Two resistances when connected in parallel, resultant value is 2 ohms. Let the two resistances be R1 and R2. So if R2 = 6ohms, then R1 = 9 - 6 = 3 ohms.
