In a series circuit, how does total resistance compare to individual resistances?

In a series circuit, the total resistance is determined by adding up all the individual resistances connected in that series. This is because, in a series configuration, the current has only one path to follow, and therefore, the resistance encountered by the current is cumulative.

When resistors are connected in series, each resistor's resistance adds to the total resistance. For example, if you have two resistors, R1 and R2, the total resistance (RT) can be calculated using the formula RT = R1 + R2. This means that if more resistors are added, the total resistance will continue to increase as each resistor contributes its value to the overall resistance experienced by the circuit.

This principle is fundamental in electronics and electrical circuit design, as understanding how resistors behave in series is crucial for creating circuits with desired characteristics, like controlling current and voltage levels.

The other choices describe different scenarios related to resistances and do not apply to series circuits. The approach of dividing the individual resistances by the number of resistors is more relevant to parallel circuits, while the product of individual resistances refers to the relationship seen in some configurations of resistances but does not apply to the total resistance in a series circuit. Lastly, the idea that total
