a) You are investigating the electrical testing circuits and find that, in an inductive circuit, the relationship between instantaneous current i (amps) and the time t (secs) is given by: -9t. i = 2.1(1 – e-⁹t) е You have been asked to determine the time taken for the current to rise from 1 to B amps. b) The drive system of a conveyor used to transport the engine parts is made up of an open belt which passes over two pulleys. The pulleys have diameters of 200mm and 320mm respectively and the distance between centres is T mm. You have been asked to determine the length of the belt, using trigonometric techniques, assuming the belt is in tension.
