A 4-ohm and 2-ohm resistor are wired in PARRELL. What is the TOTAL resistance?

1.33ohms

Explanation: The formula for resistance in a parallel circuit is :

1/Rt = 1/R1+1/R2

Where Rt represents total resistance, R1 = 4ohms and R2 = 2ohms

1/Rt = 1/4+1/2

1/Rt = 1+2/4

1/Rt = 3/4

Rt = 4/3

Rt= 1.33ohms

Hence the total resistance is 1.33ohms

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.
