In the circuit shown in the figure, the current ' T ' is
Options
- A6 ~A
- B2 ~A
- C4 ~A
- D7 ~A
Correct answer
A. 6 ~A
Step-by-step solution
Applying junction law We have array rlrl I & =I₁+I₂ 24-V 3 & = 10-V 2 + 9-V 1 & 24-V 3 & = 28-3 V 2 & 2(24-V) & =3(28-3 V) & 48-2 V & =84-9 ~V & 7 V & =36 & V & =5.14 ~V array From Ohm's law gathered V=I R V=24-5.14=18.86, R=3 I= 18.86 3 6 ~A gathered
