Equivalent resistance for resistors in series:
Two resistors in Series
Consider the setup shown of two ideal ohmic resistors. (Figure 1).
Resistor 1 has resistance R1, and resistor 2 has resistance R2. They are connected in series with a constant voltage of magnitude V. When the two resistors are connected in this way, they form a system equivalent to a single resistor of resistance R, as shown in the next diagram. (Figure 2).
What is the effective resistance R of the two-resistor system?
Express the effective resistance in terms of R1 and R2.
