Question

Is effective resistance and equivalent resistance the same? If not, what's the formula for each?

A. Yes, they are the same.
B. No, and the formula for effective resistance is R = R1 + R2.
C. No, and the formula for equivalent resistance is 1/R = 1/R1 + 1/R2.
D. No, and the formula for equivalent resistance is R = R1 * R2 / (R1 + R2).

Answer 1

The equivalent resistance and effective resistance are not the same. The formula for the equivalent resistance of two parallel resistors is R = R₁ * R₂ / (R₁ + R₂). The formula for the effective resistance of resistors in series is the sum of the individual resistances.

Step-by-step explanation:

The equivalent resistance and effective resistance are not the same.

The formula for the equivalent resistance of two parallel resistors with resistance R₁ and R₂ is: R = R₁ * R₂ / (R₁ + R₂).

The formula for the effective resistance of resistors in series is the sum of the individual resistances: Requiv = R₁ + R₂ + ... + RN.
