Question
A current source Is(t) = 15 cos(377t) is connected to terminal A and B. If L1 = 5mH, L2 = 10mH, and L3 = 15 mH, determine Vl(t), V2(t), V3(t). Write a KVL equation to determine the voltage across the current source Vs(t). A thin, plane-convex tens is made glass of refractive index 1.52. Ils curved surface bas A radius of curvature of 14.0 cm. An object is placed 32.0 cm to the left of the lns, on the formation of the image Is the image real or virtual? Is it erect or inverted? Where is was to the right of the lens. on the same side as the plane surface?Explanation / Answer
Here, 1/f = (1.52 - 1) * (1/14 - 0)
=> f = 26.92 cm
=> 1/v = 1/26.92 - 1/32
=> v = 169.57 cm
=> image is located = 169.57 cm (right of lens)
=> image is real and inverted .
For 2nd case
=> image is located = 32 cm (left of lens)
=> image is virtual and erect .
