What is the total resistance of two resistors connected in series where R1 = 40 Ohms and R2 = 10 Ohms?

To find the total resistance of two resistors connected in series, you simply add their resistances together. This is because in a series circuit, the current has only one path to follow and must pass through each resistor sequentially, causing the total resistance to be the sum of the individual resistances.

In this case, with R1 being 40 Ohms and R2 being 10 Ohms, the calculation is as follows:

Total Resistance (R_total) = R1 + R2

R_total = 40 Ohms + 10 Ohms = 50 Ohms

Thus, the total resistance for the series connection of these two resistors is 50 Ohms, which aligns with the reasoning provided to support the correct answer.
