Longer line in the symbol for a cell represents its ___________ terminal.Fill in the blank.
Topic: Electric Current
Answers
answer : Longer line in the symbol for a cell, represents its positive terminal.
explanation : A cell is electrical appliance which is used in electrical circuit to provide potential difference across two terminals. cell converts chemical energy into electrical energy. potential difference between two terminals of cell is known as electromotive force (emf ) of the battery.
see diagram, here it is clearly shown that longer line in the symbol for a cell represents its positive terminal while shorter line in the symbol for a cell represents its negative terminal.
Answer:
Longer line in the ‘symbol for a cell’ represents its positive terminal.
Explanation:
A cell in physics represents a single electric energy source that initiates a chemical reaction to produce current energy. A cell always has a positive and negative terminal. Hence it is represented by two vertical bars of different sizes.
Since ‘electricity’ flows from the ‘positive terminal’ to the negative terminal the positive terminal is represented by the longer straight line. Just parallel to it is vertically drawn a smaller straight line that represents the ‘negative terminal’.
