Question

How do you make a mixed circuit with four resistors and at least one series circuit and at least one parallel circuit in? Thank you!

We could make this as an exercise for a practical exercise we were going to do. But I have no idea how to make a circuit?

(Also the teacher said we should use these values for the resistors:
R1 = 22 Ohm
R2 = 10 Ohm
R3 = 220 Ohm
But after that, she said that all four resistors should have the same value. Maybe, I understand that incorrectly, but I don't know what she meant...)

Answer 1

Circuit Looks like figure below

It is a mixed circuit with four resistors `R_1, R_2,R_3 and R_4`.
It has at least one series circuit (say of `R_1andR_2)` and at least one parallel circuit of `R_3and R_4`. Voltage is to be applied at the two end points.

Values of `R_1, R_2 and R_3` are as given in the question.
Other conditions need to be given to work out value of `R_4`

Per second comment, the circuit is understood as given below

Here we have two parallel combinations of `R_1 and R_2` and of `R_3 and R_4`. These two parallel combinations are in series with each other.
In this circuit one may choose any one value of these resistors, the total resistance of the overall combination as seen at the end points will also be same.
