PHL271H1 Chapter : detailed summary notes for equality

In the circuit shown in the figure below, each battery isdelivering energy to the circuit by electrical transmission. Allthe resistors have equal resistance.

(a) Rank the electric potentials at points a, b, c, d, e, f, g, andh from highest to lowest, noting any cases of equality in theranking. Use only ">" or "=" symbols. If any elements are equal,show their equality in alphabetic order (for example:a>b=c).


(b) Rank the magnitudes of the currents at the same points fromgreatest to least, noting any cases of equality. Use only ">" or"=" symbols. If any elements are equal, show their equality inalphabetic order (for example: a>b=c).

Problem 6.
A) For a fixed focus camera to take clear pictures, the objectdistance must satisfy a certain inequality. What is this
inequality?
B) Why do older people need reading glasses or bifocals?

How can political philosophy help us to achieve a balance between liberty and equality?
