In the thin lens equation first prove that Zz = f*f (Hint use this diagram along with the characteristics of similar triangles). Then use this equation along with the act that Z^ = Z + f, z^ = z + f to prove the thin lens equation, which is equation 2.2 in the book. What are the two values of z^ for the cases where Z^ is plus infinity, and where Z^ = f.
Disadvantages of Low Power factor Greater conductor size : To transfer or distribute a fixed amount of power at constant voltage, the conductor will have to carry more current

Sol: The incident angle is 45 because the angle of reflection and angle of incident is equal.
Q. Point out the direction of the current if any induced to flow in the loop by the changing magnetic field. (Describe is the loop as viewed from above.)s Answer: 1.
Voltmeters: Voltmeters are used to measure emf's and more commonly potential differences. The two probes of the meter are therefore connected to the two points between which th
