Answer:
Step-by-step explanation:
To make v the subject of the formula 1 = v / r, we can rearrange the equation to isolate v on one side.
Step 1: Multiply both sides of the equation by r to eliminate the denominator:
1 * r = v / r * r
This simplifies to:
r = v
Step 2: Now that we have v isolated, we can substitute the given values into the equation to find the voltage when l = 2 and r = 6.
Replacing r with 6:
6 = v
Therefore, when l = 2 and r = 6, the voltage (v) is equal to 6.
