Question

13. Read the following passage and answer the questions from 13(i) to 13(iii). (1x3=3)
Defined in the context of static electricity, voltage or potential difference is the
measure of work required to move a unit charge from one location to another, against
the force which tries to keep electric charges balanced. In the context of electrical power
sources, voltage is the amount of potential energy available (work to be done) per unit
charge, to move charges (electrons) through a conductor. The flow of electrons is called
electric current.
Because voltage is an expression of potential energy, representing the possibility or
potential for energy release as the charge moves from one "level" to another, it is
always referenced between two points. Consider the water reservoir analogy:
