In order to determine the equivalent between points A and B when R=3, we need to analyze the given circuit diagram and apply Ohm's Law.
1. First, let's break down the circuit and identify the different elements:
- There are three resistors, each labeled with an "R" symbol.
- The resistors are connected in series, meaning the current flows through them one after another.
- Points A and B are the two ends of the circuit where we want to find the equivalent resistance.
2. Calculate the equivalent resistance (Req) using the formula for resistors in series:
- When resistors are connected in series, their resistances add up.
- Since there are three resistors with a resistance of R each, the equivalent resistance is 3R.
3. Substitute the given value for R:
- Since R = 3, the equivalent resistance (Req) between points A and B is 3R = 3 * 3 = 9 ohms.
Therefore, the equivalent resistance between points A and B is 9 ohms when R=3.
