Question Detail
Question
Three resistors (2Ω, 4Ω, 5Ω) are connected in parallel with a potential difference of 20V maintained across them. Find the total current.
Correct Answer
Option D is the correct answer.
Detailed Explanation
1/R_eq = 1/2 + 1/4 + 1/5 = 0.95, so R_eq ≈ 1.053Ω, and I = V/R_eq = 20/1.053 ≈ 19A.
Hint
Find the equivalent parallel resistance first, then apply Ohm's law with the given voltage.
