What is the output voltage of a potential divider with a total voltage of 24V and resistances of 6Ω and 4Ω?.
- A.9.6V
- B.14.4V
- C.18V
- D.24V
Model answer
What a good answer should say
- 14.4V
Explanation
Why this works
Using the formula V_out = V_total * (R2 / (R1 + R2)), where V_total = 24V, R1 = 6Ω, and R2 = 4Ω. Substituting gives V_out = 24 * (4 / (6 + 4)) = 24 * (4 / 10) = 9.6V.
