ok so we have 5 ohm and 20 ohm , in parallel, which are both in series with 50ohm

now for equivalent resistance in parallel

1 / R eq= 1/R1 + 1/R2

ie R eq= R1 * R2 / ( R1+R2)

therefore we have ( 4ohm in series with 50 ohm)

then R eq= 54ohm ( add them when in series )

then apply v=IR to get total current in circuit

I= V/R
= 12 / 54

now when this current gets to the section where it splits in two, the current is divided and the majority of current goes throguh the least resistance

current through 5ohm = 20 / ( 25) * 12 / 54
current through 20ohm = 5 / ( 25) * 12/54

Your calculations are correct.

Hello FCB,

I would be happy to help with any questions you have about parallel circuits. Can you provide more specific information about the problem you are working on, such as the circuit diagram or specific equations you are using? Also, have you tried reaching out to your teacher or classmates for assistance? It can be helpful to discuss the problem with others and collaborate on finding a solution. Good luck with your exams!
