In the circuit shown, the current source supplies I=3 A to the parallel resistors R1=12, and R2=24, . Find the current through R2.

  1. 2 A
  2. 1.5 A
  3. 0.5 A
  4. 1 A

Answer

D. 1 A

Solution

The voltage across the parallel group is V=I,Req with Req=8, , so V=(3 A)(8, )=24 V. Then I2=V/R2= 24 V24, =1 A.
