Quizplus · Accepted Answer

In a series circuit, the resistors are connected end to end, so the current flows through each resistor one after the other. According to Ohm's law, the voltage drop across each resistor is proportional to its resistance value. Therefore, the total voltage drop across all the resistors is equal to the sum of the voltage drops across each resistor. Similarly, the current flowing through each resistor is the same, so the total current is equal to the current flowing through each resistor. Finally, the total resistance is the sum of the resistance values of all the resistors in the circuit, as stated in the rule.
