When two or more resistors are connected in series to a battery
A) the same current flows through each resistor.
B) the total voltage across the combination is the algebraic sum of the voltages across the individual resistors.
C) the equivalent resistance of the combination is equal to the sum of the resistances of each resistor.
D) all of the other choices are true.

Question

Quizplus · Accepted Answer

When resistors are connected in series, the same current flows through each resistor due to the continuity of the circuit, the total voltage across the combination is indeed the sum of the voltages across each resistor (as per Kirchhoff's voltage law), and the equivalent resistance is the sum of the individual resistances. Therefore, all the given statements are true for series circuits.
