Answer:
I=0.02[amp]
Explanation:
Since the resistors are connected in series, we can find the total resistance.
[tex]Rt = 100 + 300+50\\Rt = 450[ohm][/tex]
Now we can use ohm's law which tells us that the voltage is equal to the product of resistance by the current.
[tex]V =I*R\\I=V/R\\I=9/450\\I=0.02[amp][/tex]
