Full-wave rectifier: The circuit diagram of a full-wave rectifier is shown in figure. The a.c. to be rectified is fed to the primary terminals of a centre-tapped transformer.

During the first (positive) half cycle of the a.c. input, the upper end of the secondary coil acquires positive potential and the lower end acquires negative potential. As a result, diode gets forward biased and diode gets reverse biased. Diode conducts and a current flows through load, as shown by continuous in Figure.

During the next (negative) half cycle of the a.c. input, the upper end of the secondary coil acquires negative potential and the lower end acquires positive potential. As a result, diode gets reverse biased and diode gets forward biased. Diode conducts and a current flows through load, as shown by dotted lines in figure. The direction of current remains same as in the previous half cycle.
The circuit diagram of full wave rectifier is shown below.

5 points Infinite square well. The infinite square well in this problem is given by the potential energy V(x) as described on the formula sheet. (a) The loosely bound electrons in the linear carbon chain part of the retinal molecule (discussed briefly in class) are free to move only within this region. This linear chain has a length of a. Explain briefly how the Infinite square well can model this system. (b) If a photon is absorbed by a particle in the square well and is raised from the ground state to the first excited state, what is the energy E of the photon that corresponds to this transition? Express E in terms of a, the particle mass m, and h. (c) What is the most probable position to find the electron along the chain before and after the photon is absorbed by the linear part of the linear retinal chain? Let a=0 be one end of the chain and x=a be the other end. Express the answer in terms of a fraction of a.
