Proposed Exercises: Thevenin and Norton Theorem Find the Thevenin and Norton equivalent of the circuit shown below.
Consider ₁ = 12 , ₂ = 24 , ₃ = 7 , = 18 and = 2.25 . Draw
also the equivalent circuits of Thevenin and Norton.

Ascientist notices that an oil slick floating on water when viewed from above has many different colors reflecting off the surface, making it look rainbow-like (an effect known as iridescence). she aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). the index of refraction of water is 1.3
