Question

What is the equivalent resistance of a parallel circuit containing the following resistors: 10 ohms, 10 ohms, 10 ohms, and 10 ohms?

Answer 1

Answer:2.5ohms

Explanation:

Let them equivalent resistance be R

1/R=1/r+1/r+1/r+1/r

1/R=1/10+1/10+1/10+1/10

1/R=4/10

Cross multiplying we get

4R=10

Divide both sides by 4

4R/4=10/4

R=10/4

R=2.5ohms
