From the given I-V characteristics of a silicon diode, what is the approximate value of rav between marked points?

From the given I-V characteristics of a silicon diode, what is the approximate value of rav between marked points? Correct Answer 7 ohms

rav is the average AC resistance, found between two marked points in the I-V graph. Here rav=0.1/14mA=7Ω.

Two circular dials of exactly the same size are mounted on a wall side by side in such a way that their perimeters touch at one point. Dial 1, which is on the left , spins clockwise around its center , and dial 2 , which is on the right spins counter clockwise around its center . (Assume that there is no friction at the point of contact between the dials.) Each dial is marked on its perimeter at three points that are at equale distances around the points arked ondial 1 are N, O, and P and the points marked on dial 2 are X, Y, and Z. If points O and Z are just meeting at the point of contact between the dials , and if dial 1 spins at the same speed as dial 2, what is the smallest number of revolutions of each dial that will bring O and Z together again?

Given below are three quantities named A, B and C. Based on the given information, determine the relation among the three quantities. Quantity 1: The marked price of a timex sports watch was Rs.720. A man bought the same for Rs. 550.80 after getting two successive discounts, the first being 10%. What was the second discount rate? Quantity 2: The shopkeeper sold his good at half the list price and thus lost 20%. If he had sold on the listed price, find the gain percent. Quantity 3: The timber trader marked his good at 20% above the cost price. He sold half the stock at the marked price, one quarter at a discount of 20% on the marked price and the rest at the discount of 30% on the marked price. Find the total gain.
The line chart given below shows the marked price and selling price of six articles A, B, C, D, E and F. Discount = (Marked price - selling price) Discount% = \( \rm\frac{Marked price-Selling price}{Marked price} \times 100\) J1 = Value of sum of discount on articles C and D J2 = Value of difference of discount on articles D and E What is the value of J1 - J2?
