Explanation :
An electrical circuit can be either connected in series or parallel.
Series combination: The current flowing in each resistor is the same and the equivalent resistance is given by :
[tex]R{eq}=R_1+R_2+R_3+.................+R_n[/tex]
Parallel combination: The voltage for all components in the parallel combination is the same. The equivalent resistance is given by :
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_{1}}+\dfrac{1}{R_{2}}+\dfrac{1}{R_{3}}......................+\dfrac{1}{R_{n}}[/tex]
So, our of given options the correct one is (b) because the current flowing in both the resistors is the same.
