For the circuit shown, I=10 A, R1=5, , and R2=15, . Find the Norton current IN at terminals a-b.
- 2.5 A
- 10 A
- 7.5 A
- 5 A
Answer
A. 2.5 A
Solution
Short terminals a-b. Then R1 and R2 are in parallel across the current source, so the source current divides between them, and IN is the part flowing through R2: IN=IR1/R1+R2=(10 A)5, /5, +15, =2.5 A.
