Urgent, Kirchoff question
DaBit, this is something for you and for the other smart guys here around.
My son has tomorrow an exam of electronics.
In his study book, he found a question which he can't solve.
He hopes that they don't ask this question.
See picture in attachment.
He knows that the solution should be 50 ohms.
Can someone explain why please?
Question is: what should be the value in ohms of RX so that the current through Rx should be the same as I R1 (current through the 80 ohms resistance)
