Before solving this question, we need to know about the Series and parallel connection or arrangement of resistors. Series means side by side:
-------------[R1]----------[R2]-------------- In this arrangement the current remains constant but Potential difference varies.
✒To find Equivalent resistance:
Parallel means in a parallel pattern:
----------[R1]--------
----------[R2]------- In this arrangement, the current varies, it gets divided whereas potential difference remains same.
By keeping these concepts in mind, let's solve this question.
Here,
So, by using formula,
Equivalent resistance of 4Ω and 8Ω:
Equivalent resistance of xΩ and 8Ω:
According to question,
And Total Equivalent resistance is 4Ω
By using formula,
Hence, resistance of x is 1Ω.
