Question: 1 / 400

When R1 and R2 are connected in series, what is the total resistance?

R1 - R2

R1 + R2

When resistors R1 and R2 are connected in series, the total resistance is the sum of the individual resistances. This is due to how series circuits work: the current flowing through each resistor is the same, and each resistor adds to the overall restriction of current flow. Therefore, the total resistance can be calculated simply by adding the values of R1 and R2 together.

In a series configuration, if one resistor has a resistance of 3 ohms and another has a resistance of 2 ohms, the total resistance would be 3 + 2 = 5 ohms. This principle is important as it directly influences how circuits behave and how voltage and current are distributed across the components in the circuit. Knowing this fundamental concept is crucial in electrical applications and analysis.
