A 2 ohm resistor is connected in parallel with a 4 ohm resistor. What is their equivalent resistance?
Q1. A 2 ohm resistor is connected in parallel with a 4 ohm resistor. What is their equivalent resistance?
Answer: 4/3 ohm
Explanation: Using the formula for parallel resistors, 1/R_eq = 1/2 + 1/4 = 3/4, so R_eq = 4/3 ohm. Option A is incorrect because it incorrectly calculates the equivalent resistance.
