If two resistors in series are equal, say R each, what is the total resistance?
Correct Answer:
B. 2R
Explanation:
The correct answer is Option B: 2R.
When resistors are connected in a series circuit, the total or equivalent resistance is calculated by summing the individual resistance values. In this scenario, there are two resistors, each with a resistance of R. Therefore, the total resistance is found by adding R + R, which equals 2R. In a series arrangement, the total resistance will always be greater than any individual resistor's value because the current must flow through each component sequentially.
