Question

3. Which of these is not a circuit element? 1m
(a) potential difference
(b) voltmeter
(c) resistor
(d) battery or
A point A in a circuit is at a lower potential than point B. In which direction will the current flow in the
circuit? 1m

Answer 1

Answer:

a. potential difference

Current always flows from a point of higher potential to lower potential. So the current will flow from point B to A, as point A is at lower potential than A thus it makes point B at a higher potential and hence the direction of the flow of current.

Answer 2

potential difference is the answer.
