which of the following is true of an electric charge?
a). positive charge means deficit of electrons.
b). negative charges means excess of electrons.
c). electric current means movement of electrons
d). all of the above.
e). a and b only?
To determine which statement is true of an electric charge, let's analyze each option:
a) Positive charge means a deficit of electrons: This statement is true. A positive charge occurs when an atom or object loses electrons, resulting in an overall deficit of negatively charged particles.
b) Negative charge means an excess of electrons: This statement is also true. A negative charge occurs when an atom or object gains electrons, resulting in an excess of negatively charged particles.
c) Electric current means the movement of electrons: This statement is accurate as well. Electric current refers to the flow of electric charge in a circuit, which is typically carried by moving electrons.
Now let's consider the options given:
d) "All of the above": This option encompasses all three statements mentioned above, making it correct.
e) "A and b only": This option is incorrect as it only includes the second and third statements, omitting the first statement.
Therefore, the correct answer is option d) – "all of the above" since all three statements are true regarding an electric charge.
