Study Notes
Circuit Diagram 1
- The circuit consists of three resistors: 30 Ω, 20 Ω, and 60 Ω.
- The 20 Ω and 60 Ω resistors are in parallel with each other, forming a combined resistance of 15 Ω.
- 15 Ω is then in series with the 30 Ω resistor, giving a total resistance of 45 Ω between points a and b.
Circuit Diagram 2
- The circuit is more complex, containing six resistors.
- The 30 Ω resistor and the 40 Ω resistor are in series, giving a combined resistance of 70 Ω.
- The 10 Ω resistor and the 80 Ω resistor are in series, giving a combined resistance of 90 Ω.
- The 50 Ω resistor is in parallel with the combination of the 10 Ω and 80 Ω resistors.
- This combination then combines with the 60 Ω resistor to form a parallel with the combination of the 30 Ω and 40 Ω resistors.
- This complex arrangement results in the equivalent resistance from terminal a to b being approximately 26.5 Ω.
