Vedclass · Answer

(A) When resistors are connected in series,the equivalent resistance $R_{eq}$ is the sum of individual resistances: $R_{eq} = R_1 + R_2 + R_3 + ... + R_n$. Since each resistor adds to the total,the equivalent resistance is always greater than any individual resistor.In contrast,when resistors are connected in parallel,the reciprocal of the equivalent resistance is the sum of the reciprocals of individual resistances: $1/R_{eq} = 1/R_1 + 1/R_2 + ... + 1/R_n$. This results in an equivalent resistance that is smaller than the smallest individual resistor in the circuit.Therefore,the equivalent resistance increases in a series connection.
